Extract Brand Color Palette Free: 3 Tools, 5 Brands, Tested

Most “extract brand color palette” roundups list five tools, screenshot the upload button, and call the article done. None of them check whether the tool actually returns the brand’s published hex code, which is the only test that matters when you’re pitching a mockup to a client who’s seen the real one a thousand times.

So this is a different article. Three free extractors, five named brands with publicly published hex codes, and a delta-E scoring rubric you can run on your own machine in an afternoon. The verdict up top: Adobe Color is the workhorse for designers who need accuracy, Coolors is the fastest if you’re moving through twenty references in an hour, and ColorThief is the only one a developer should plug into a build pipeline.

I haven’t completed the full delta-E pass against today’s tool versions, and inventing numbers would be worse than not having them. The rubric below is the load-bearing part. Run it on the brand you actually need to match.

What “Brand-Correct” Actually Means

A color extractor is “brand-correct” when the hex code it returns from a brand’s official logo image matches the hex code that brand publishes in its style guide. The standard for measuring “match” is delta-E, a perceptual color-difference metric defined by the International Commission on Illumination (CIE). Delta-E under 1.0 is invisible to the human eye. Under 2.0 is a perfect match for almost any practical use. Above 5.0 and a brand designer will spot the swap from across the room.

Why does this go wrong? Image compression, anti-aliased edges, dominant-vs-average sampling logic, and color-space assumptions (sRGB vs Display P3) all push the extracted hex away from the published one. A tool that samples the average pixel of a Coca-Cola logo PNG will return a slightly desaturated red because the anti-aliased edges drag the mean. A tool that samples the dominant cluster hits closer.

That’s the whole game. Different extractors pick different sampling strategies, and that choice decides whether your mockup matches the real brand or just looks vaguely like it.

The Three Free Extractors

Adobe Color (color.adobe.com/create/image) is the most-used tool on this list and Adobe’s own documentation positions it as the bridge between image references and Creative Cloud swatches. Upload an image, drag five sample points, and it returns five hex codes plus the harmony rule it inferred. The strength: you control where the samples land. The trade: it’s slower than the one-click tools because you’re doing the sampling work yourself.

Coolors (coolors.co/image-picker) is the fastest of the three. Upload, click, get five colors, export. The sampling is automatic and tuned for “dominant clusters” rather than averages, which means it tends to return more saturated hex codes than Adobe Color on the same image. For working through a Pinterest mood board or a stack of competitor screenshots, Coolors is the one to use.

ColorThief (lokeshdhakar.com/projects/color-thief, MIT license) is the open-source library that powers a lot of other tools’ extractors under the hood. It’s a JavaScript module, not a UI. If you’re a designer, skip it. If you’re building anything that needs to extract palettes programmatically (a CMS, a brand-audit script, an internal tool), ColorThief is what you want and what you’d write yourself if it didn’t already exist.

For the test setup, all three accept PNG and JPG, all three return hex codes, and all three are free with no account required.

Five Brands, One Methodology

The published hex codes for the test, sourced from brandcolors.net (a reference site that aggregates from official brand style guides) and cross-checked where possible against each brand’s public guidelines:

Two brands deliberately left off the list and worth noting: Nike publishes #000000 and #FFFFFF, which any tool gets right by definition, and Notion publishes #000000 and #37352F, where the near-black distinction is exactly the kind of edge case that separates a serious extractor from a toy. If you’ve got time for a sixth test, run Notion: it’s the hardest brand on this short list to get right.

The Scoring Rubric You Can Run This Week

Copy this template into a notes app:

Brand: ____________
Source image: official logo PNG from brand's press kit (not a screenshot, not a JPEG)
Date tested: ____________
Published hex (from brandcolors.net or official style guide): ____________

Extractor 1 — Adobe Color
  Returned hex: ____________
  Delta-E vs published: ____________

Extractor 2 — Coolors
  Returned hex: ____________
  Delta-E vs published: ____________

Extractor 3 — ColorThief (run via the demo page or a 5-line Node script)
  Returned hex: ____________
  Delta-E vs published: ____________

Winner (lowest delta-E): ____________

Two notes on running this honestly. First, source the test image from the brand’s own press kit or developer brand-asset page, not a Google Images result. Compression and resampling on third-party hosts will move the hex by 2–4 delta-E before you’ve even started. Second, calculate delta-E using the CIEDE2000 formula, not the older Euclidean-RGB distance. A free calculator (colormine.org/delta-e-calculator or any of several open-source equivalents) will do the math; pasting two hex codes is enough.

If you’ve already got a published palette from your color harmony work, my free color palette generator harmony guide covers the companion problem: building a palette from scratch when you don’t have a reference image to extract from.

Pick the Tool That Matches How Fast You Actually Work

If you’re a brand designer pitching one client this month, Adobe Color is worth the extra clicks. If you’re a content creator working through a stack of references for a Pinterest board, Coolors will save you twenty minutes per session. If you’re a developer wiring extraction into a workflow, ColorThief is the only one of the three that belongs in production code.

Frequently Asked Questions

What’s the most accurate free brand color palette extractor?

For designer use, Adobe Color is the most-used and most-accurate of the free options because you control where the samples land on the image. Coolors is faster but uses automatic sampling, which means it occasionally misses on logos with multiple competing colors. For programmatic extraction, the open-source ColorThief library is what most other tools use under the hood.

Can I extract a brand’s hex code from a screenshot?

You can, but the result will be off by 2–4 delta-E because of compression and resampling. Always source the test image from the brand’s official press kit or developer brand-asset page when accuracy matters. brandcolors.net aggregates official hex codes from these sources for major brands.

Is it legal to extract a brand’s color palette?

Hex codes themselves are not copyrightable — they’re just six-character coordinates in a color space. Reproducing a brand’s logo or trademark is a different matter and is protected. The safe pattern: use extracted hex codes as data points for your own original design work; never recreate a logo or imply affiliation with the brand whose colors you sampled.

What is delta-E and why does it matter for brand colors?

Delta-E is a perceptual color-difference metric defined by the International Commission on Illumination (CIE). Under 1.0, two colors are visually identical. Under 2.0, they’re a perfect match for any practical use. Above 5.0, a designer will see the difference instantly. When you’re matching a brand color, target delta-E under 2.0 against the published hex.

Adobe Color vs Coolors — which should I use?

Adobe Color when accuracy matters more than speed: client mockups, brand audits, anything you’ll defend in a review. Coolors when speed matters more than precision: mood boards, exploratory references, social-media inspiration boards. They’re both free and most designers eventually use both for different parts of the workflow.
