Color Name Finder

By Bogdan Sandu · Published 13 October 2025 · Last updated 14 September 2026

This Color Name Finder tells you what a color in an image is called. Upload a picture, hover over any pixel, and the panel shows the closest named color with its hex code and RGB values. The image never leaves your browser.

What it does:

• Accepts any image your browser can display, by file picker or drag and drop
• Reads the pixel under your cursor as you hover, and locks it when you click
• Matches the pixel against 259 named colors, from Red and Blue to Wine Berry, Byzantium, and Laser Lemon
• Picks the name with the smallest CIEDE2000 color difference, so the match follows how people see color rather than raw RGB distance
• Copies the name, hex, or RGB value to your clipboard with one click

How to Use This Color Name Finder

1. Click the upload area or drop an image onto it. JPEG, PNG, WebP, and GIF all work.
2. Move the cursor over the image. The swatch and the three values update as you hover.
3. Click to lock a pixel. The values stay put until you click somewhere else.
4. Use the copy button next to Name, Hex, or RGB. Click Add New Image to start over.

A cornflower-blue pixel comes back like this:

Name  Cornflower Blue
Hex   #6495ED
RGB   100, 149, 237

Pixels that fall between named colors get the nearest neighbor. A slightly different blue such as #6A94E8 still returns Cornflower Blue, and #2E8B57 returns Sea Green. A dark navy like #1B1F3B returns Dark Purple, because that is the closest entry in the list.

The match runs in three steps, all in JavaScript on your device. Convert the pixel from sRGB to CIELAB, compute the CIEDE2000 distance to each of the 259 entries, and return the smallest.

What the tool does not do

• It has no text input. To name a hex or RGB code you already have, paste it into the HEX to RGB converter for the values, or make a one-pixel screenshot of the color and upload that.
• It shows hex and RGB only. For HSL, run the hex through the HSL to RGB converter in reverse.
• It cannot pick colors from other windows or tabs. Take a screenshot first.
• The 259 names are a curated list, not Pantone, RAL, or paint-brand names. The name is a description, not a product code.
• It does not check contrast or simulate color blindness. The accessible color palette generator covers contrast.

What Is a Color Name?

A color name is the human-readable identifier assigned to a specific set of color values within a standardized color system.

Names like "crimson," "slate blue," or "forest green" make colors memorable and communicable. Numerical codes like #DC143C are precise but meaningless to most people.

The W3C defines 148 named colors in CSS that browsers universally recognize. These names map directly to specific hex codes.

Different industries use different naming systems. Pantone serves print and product design. RAL dominates industrial applications. The NCS color system structures architectural specifications.

What Is a Color Name Finder?

A color name finder is a tool that takes a color value and returns its closest matching human-readable name.

Feed it a hex code, an RGB value, or a pixel sampled from an image, and it hands back something like "tomato" or "steel blue" instead of a string of numbers.

It is not a palette builder, and it does not generate new color schemes.

Its one job is translation. Numeric value in, name out.

Most tools in this category pull from a fixed, predefined list of named colors rather than inventing labels on the fly. Input usually arrives one of three ways:

• Hex, RGB, or HSL code entry
• Image upload for pulling a name from a photo, which is how the tool above works
• Screen or eyedropper picking

The output typically includes the matched name, the original code, and sometimes a confidence score showing how close the match really is.

ColorHexa is a good example of this in practice. Type in a hex code and it returns a name instantly, with no configuration involved.

Color Name Finder vs Color Picker: What's the Difference?

A color picker extracts a numeric value from a color, nothing more.

A color name finder takes that value a step further and maps it to a name.

Color picker: outputs hex, RGB, or HSL numbers only.

Color name finder: outputs a name, usually alongside the numbers.

Multiple tools blend both functions into one interface, so the line between them gets blurry in daily use.

Google Chrome's built-in inspector ships a color picker with an eyedropper. It stops at the numeric value and leaves naming to a separate tool entirely.

The distinction matters most at handoff. A designer writing "cornflowerblue" in a spec communicates faster than one pasting #6495ED into a comment thread. That is especially true when the notes feed into interface design documentation that non-technical stakeholders also read.

What Color Naming Standards Does a Color Name Finder Use?

A color name finder pulls its vocabulary from a fixed naming standard. The standard chosen sets both the vocabulary and the precision of the match.

Four systems show up most often: X11, Pantone, RAL, and ISCC-NBS.

Standard	Governed By	Approximate Size	Primary Use
X11 / CSS	World Wide Web Consortium	148 names	Web and UI design
Pantone	Pantone LLC	2,000+ colors	Print and branding
RAL Classic	RAL gGmbH	216 colors	Industrial, architecture
ISCC-NBS	Inter-Society Color Council	267 categories	Scientific description
This tool	Curated list	259 names	Naming colors in images

Most free, browser-based tools default to the X11 list because it's baked directly into CSS, formalized in the CSS Color Module Level 4 specification from the W3C. This tool uses its own curated list of 259 names instead.

Pantone and RAL sit outside the browser entirely. Both are licensed systems built for physical materials like ink and paint rather than screen pixels.

Paint brands complicate things further. Sherwin-Williams and Behr each run their own proprietary naming systems, so a swatch called Agreeable Gray won't show up in X11, Pantone, or RAL at all.

The same hex code can carry a different name depending on which standard a tool is built against. That's the actual reason two color name finders sometimes disagree on identical input.

How Does a Color Name Finder Match a Color to a Name?

Most color name finders use nearest-neighbor lookup. They take the input color, compare it against every entry in the naming database, and return whichever name sits closest.

"Closest" isn't measured in raw RGB units on the better tools.

Colors get converted into CIELAB or a similar perceptually uniform space first, then compared using a formula called Delta E. It approximates how a human eye perceives difference rather than how a computer stores it.

1. Convert the input from sRGB into CIELAB or CIE XYZ
2. Calculate the Delta E distance to every named color in the list
3. Return the name with the smallest distance

A Delta E of roughly 2 or below is generally the point where two colors become hard to tell apart for most people. This tool uses CIEDE2000, the 2001 revision of the formula, which corrects the older versions' bias in the blue and neutral ranges.

Tools running plain RGB distance instead of Delta E get hue-heavy mismatches wrong more often. This shows up especially in the blue and green ranges, where human perception and raw pixel math diverge.

Name That Color, a project built by developer Chirag Mehta, runs this same nearest-neighbor logic against a curated list of common color names.

Some tools expose this matching logic through an API. Developers can then run the lookup server-side instead of shipping the whole naming database to the browser.

What Input Methods Does a Color Name Finder Accept?

Input method determines how a value gets into the tool in the first place. Many color name finders support more than one at once; this one is image-only.

Hex and RGB/HSL Code Entry

Hex: a six-digit code like #6495ED, the most common format pasted from design tools.

RGB: three numbers between 0 and 255 for red, green, and blue.

HSL: hue, saturation, and lightness, closer to how a person describes a color out loud.

A tool built to accept all three usually runs an HSL to RGB conversion behind the scenes before the match ever runs. The naming database itself is stored in RGB or hex.

Image Upload

Upload a photo or a design file, and the tool samples pixels directly instead of waiting for a typed code.

Simple tools, this one included, grab the color under a click point using the canvas pixel-reading logic built into the browser.

More advanced ones run k-means clustering across the whole image first, to pull out the dominant colors before naming each one.

• JPEG and PNG, the two most common uploads
• WebP, increasingly common from modern export tools
• SVG, though flat vector fills sample more predictably than photos

Files exported for print sometimes arrive in CMYK rather than RGB. A CMYK to RGB conversion step has to run before any matching can happen, since most naming databases only speak RGB.

Eyedropper and Screen Color Picking

Browser-based: Chrome and other Chromium browsers ship a built-in EyeDropper API, letting a user click any pixel on screen, in any open app, without installing an extension.

Design software: Adobe Photoshop and GIMP both include a native eyedropper tool for pulling values straight from a canvas.

Screen picking skips typing entirely. That makes it the fastest input method whenever the color already exists somewhere visible rather than as a written code.

How Accurate Is a Color Name Finder?

Accuracy comes down to two things: how the distance is calculated, and how large the naming database actually is.

A denser list draws finer lines between similar shades. A 148-name list will call two closely related blues by the same name where a 2,000-plus name list tells them apart.

• 148 named colors in the CSS Color Module Level 4 specification
• 2,000+ colors in the Pantone Matching System library
• 216 colors in the RAL Classic collection
• 267 categories defined by the ISCC-NBS naming system
• 259 names in this tool's list
• About 2 Delta E is the typical just-noticeable-difference threshold

A tool running on the 148-name CSS list will always feel less precise than one running against Pantone's full library, simply because it has fewer names to pick from.

Screen calibration adds another layer of drift. The same hex code can render slightly warmer or cooler depending on the monitor. That shifts the perceived match even when the underlying number never changes.

Choosing a Color Naming Standard for Your Project

The right standard depends on where the color actually ends up: a browser, a printed page, or a physical material like paint or powder coating.

For Web and UI Design

X11 / CSS is the default for anything rendering in a browser, since the names are recognized directly by CSS without any extra library.

• Free and built into every browser
• Names map directly to hex values developers can paste into code
• Limited to 148 names, so nuance between close shades gets lost

Once a color is chosen, moving it from a design file into code usually means an RGB to hex conversion, so it matches what CSS expects.

For Print and Branding

Pantone dominates here because it solves a problem X11 was never built for. It gets the same color to look identical across different printers, materials, and countries.

Pros: tight color consistency across production runs, a much larger library, and direct integration into Adobe Illustrator, InDesign, and Photoshop through Pantone's own extension.

Cons: the system is licensed, physical guides cost money, and it has no native meaning to a browser or a CSS file.

RAL plays a similar role for architecture and industrial products, favored for powder coatings, signage, and anything manufactured rather than printed.

Pros: an extremely precise numbering system, and the standard reference across Europe for coatings and plastics.

Cons: almost unknown outside industrial and architectural contexts, and it carries the same licensing friction as Pantone.

For Accessibility and Contrast Work

X11 and CSS names stay the practical choice here too. Accessibility documentation usually needs to reference the same keyword a developer will type into a stylesheet.

Pairing a name finder with an accessible color palette generator keeps the chosen names tied to combinations that also clear contrast requirements. That beats picking a name first and checking contrast as an afterthought.

How to Find a Color Name Step by Step

The process is short no matter which input method is used, though a few extra steps sneak in depending on the source. The tool on this page covers the image route; the code route needs a tool with a text field.

Finding a Color Name from a Hex or RGB Code

This is the fastest path, since there's no file to prepare and no pixel to sample.

1. Paste the hex code or RGB value into the input field
2. Let the tool convert it into the naming database's internal color space
3. Read the returned name alongside the original code

A common mistake trips people up here. People paste an 8-digit hex value, which includes an alpha channel, into a field built for the standard 6-digit format.

The CSS Color Module Level 4 specification added 8-digit hex support for transparency, but not every color name finder parses that extra pair of digits correctly.

Adobe Color handles this cleanly. Type in a 6-digit hex code and it returns the nearest named swatch instantly, without touching alpha values at all.

If the final destination is a printed piece rather than a screen, the matched value still needs an RGB to CMYK conversion before it goes anywhere near a printer.

Finding a Color Name from an Image

Image-based matching adds one step at the front: getting a single pixel value out of a whole picture.

1. Upload the image file, or paste in a URL on tools that accept one
2. Click a point on the image, or let the tool auto-detect dominant colors
3. Run that sampled value through the same naming lookup used for typed codes

Browser-based tools typically read the uploaded file as an HTML image element before sampling any pixels from it.

• JPEG files compress color data more aggressively than PNG
• Screenshots usually carry the exact color intended, with no compression loss

Sampling from a heavily compressed JPEG can return a name that's technically correct for the pixel, but not for the color the original designer used.

Checking Color Accessibility and Contrast with a Color Name Finder

Naming a color and confirming it's usable are two different checks. A growing number of tools now run both in the same interface, though the finder on this page sticks to naming.

Contrast checking sits inside broader web accessibility work, while a name finder handles the labeling side of the same workflow.

Contrast Ratio Checking

Contrast ratio measures the luminance difference between a foreground color and its background, formalized as part of WCAG's color contrast requirements.

Text Type	Level AA	Level AAA
Normal text	4.5:1	7:1
Large text	3:1	4.5:1

WCAG sets these as the floor for Success Criterion 1.4.3.

A color name finder that reports "sky blue" says nothing about whether sky blue text on a white background actually clears that 4.5:1 threshold.

Colorblind Simulation

Roughly 1 in 12 men (8%) and 1 in 200 women (0.5%) worldwide have some form of color blindness, according to Colour Blind Awareness.

Most cases fall into one of three categories.

• Protanopia, reduced sensitivity to red
• Deuteranopia, reduced sensitivity to green
• Tritanopia, reduced sensitivity to blue, far rarer than the other two

Simulation features apply a filter that mimics one of these deficiencies over a chosen palette. They show whether two named colors that look distinct to most people collapse into the same shade for someone with red-green color blindness.

Clinical screening for the condition still relies on the Ishihara test, a set of dot-pattern plates that a simulation feature approximates visually rather than diagnostically.

When a Color Name Finder Does Not Work

A color name finder can fail even when every step runs correctly, because some of the variables sit outside the tool entirely.

Uncalibrated, wide-gamut displays render the same hex value with more saturation than intended. The browser doesn't always color-manage sRGB values correctly on a wider screen.

Compressed image formats alter pixel data before any sampling happens. JPEG's chroma subsampling averages color information across blocks of pixels, so a sampled point can shift slightly from the color a designer used.

Physical materials introduce a problem no naming database can solve on its own: metamerism. Two colors that match under one light source stop matching under another.

Browser feature gaps block entire input methods outright. The EyeDropper API, shipped in Chrome 95, remains unsupported in Firefox and Safari according to caniuse.

The matching logic itself typically runs in JavaScript inside the browser. A feature the browser doesn't expose is simply unavailable, no matter how good the naming database behind it is.

None of this makes the output useless. It means the name returned is an approximation of a specific numeric value, not a certified match to a physical object on a desk somewhere.

FAQ on Color Name Finders

Is There a Universal Standard for Color Names?

No single standard exists. X11, Pantone, RAL, and ISCC-NBS each define their own names for different mediums. None acts as a global naming authority.

Most projects choose a standard based on where the color will be used.

Can a Color Name Finder Identify Pantone or RAL Codes Specifically?

Most free, browser-based tools, this one included, only match against X11 or a custom curated list, not Pantone or RAL.

Getting an exact Pantone or RAL code requires a licensed color-matching tool or a physical swatch book, not a standard web name finder.

What's the Difference Between Web-Safe Colors and Pantone Names?

Web-safe colors are a fixed set of 216 shades from the 256-color display era, chosen to render identically across old monitors. Pantone names describe physical ink formulas used in print production.

The two systems don't map onto each other.

Does a Color Name Finder Help Colorblind Users?

Returning a text label instead of a swatch helps, since a name like forest green doesn't require distinguishing hues visually. It doesn't correct color vision deficiency.

Pairing the name finder with a colorblind simulation feature covers what plain naming cannot.

Can a Color Name Finder Match Real Paint Colors Accurately?

Treat the result as a starting point, not a final answer. Lighting, monitor calibration, and the paint's own finish all change how a color reads in person.

Confirm any online match against a physical sample before committing.

How Does Color Name Finder Handle Changing Naming Standards?

A color name finder keeps working after a naming standard changes only by re-pointing its matching database to the updated list. The tool itself holds no built-in awareness of a standard's revision history or version number.

ISCC-NBS's 267 named categories sit closer in scale to the CSS list's 148 names than to Pantone's 2,000-plus library. That positions it as a scientific middle ground between web shorthand and industrial-grade precision.

CSS Color Module Level 4 remains a W3C Candidate Recommendation Draft as of September 2026, not yet a finalized Recommendation. Its named-color list has been stable since rebeccapurple was added, so a finder built on it is unlikely to change its answers soon.

Once a name is confirmed, a workflow still needs the underlying numbers in a different format. That is where a hex to RGB conversion becomes the next practical step.
