Extract Colors from Image — Free Online Color Picker Tool

Extract Colors from Any Image, Right in Your Browser

Sometimes you do not need a whole design system — you just need to know the exact colors in an image. Maybe it is a client's logo, a screenshot of a UI you like, or a photo whose mood you want to reuse. TooStamply's tool lets you extract colors from image files instantly, returning precise HEX, RGB, HSL, and OKLCH values for every color it finds. It is free, needs no signup, and works entirely in your browser, which makes it a fast, private image color extractor in 2026.

This guide explains how the extraction works, what values you get, and how to export them into real code.

How Color Extraction Works

A naive approach would sample a few random pixels and hope for the best. TooStamply does something smarter: it runs a k-means clustering pass (color quantization) that groups every pixel into a small set of representative colors, weighted by how much of the image each one covers. The result is a coherent palette that reflects the image's true color distribution rather than one stray bright pixel.

That is the difference between a simple color picker from image and a real color palette extractor from image: the former grabs whatever is under your cursor, while the latter understands the whole picture. TooStamply gives you both — click any point to sample an exact color, or let the algorithm surface the dominant ones for you.

Supported Image Formats

• JPG / JPEG — photos and screenshots.
• PNG — logos, illustrations, and UI mockups with transparency.
• SVG — vector graphics.
• WebP — modern, compressed web images.

What You Get for Every Color

For each extracted color, this color detector returns a full set of values so you never have to convert by hand:

Having OKLCH alongside the classic formats matters when you plan to build shade scales later — it is the same color space our Tailwind color palette generator uses to generate even, natural-looking steps.

Export Options

As a proper color analyzer, TooStamply lets you copy your extracted colors in whatever format your project speaks:

• CSS custom properties
• Tailwind CSS config (v3 and v4 @theme)
• SCSS / Sass variables
• Bootstrap 5 overrides
• Flutter Color constants
• React Native color objects
• Plain HEX/RGB/HSL text lists

A one-click CSS export looks like this:

:root {
  --color-1: #3b82f6;
  --color-2: #1e293b;
  --color-3: #f59e0b;
  --color-4: #f8fafc;
}

And for a Flutter app, the same colors come out as Dart constants:

// Flutter export
const Color color1 = Color(0xFF3B82F6);
const Color color2 = Color(0xFF1E293B);
const Color color3 = Color(0xFFF59E0B);

Built-in Accessibility Check

Because the tool already computes contrast ratios, you can confirm accessibility while you extract. Every color's ratio against white and black is shown, and if you pair two swatches, the WCAG contrast checker tells you whether the combination passes AA (4.5:1 for normal text) or AAA (7:1). That turns a separate accessibility audit into a check you make in the moment.

Common Use Cases

• Web designers — base a site palette on a brand photo or hero image.
• Graphic designers — match colors precisely from a reference image.
• UI/UX designers — pull exact values from Figma or Sketch screenshots.
• Artists — study the color relationships in reference art.
• Marketers — keep brand colors consistent across every material.

Once you have your colors, you can refine them into full color schemes or explore harmonies on the color wheel. If you want the algorithm to build a complete, tuned palette instead of raw swatches, the color palette generator takes the same image further.

Privacy by Default

Your image is processed entirely in your browser. Nothing is uploaded to any server, nothing is stored, and closing the tab removes the image for good. For anyone extracting colors from confidential logos, unreleased designs, or client work, that client-side approach is not a nice-to-have — it is the whole point.

Frequently Asked Questions

Is this color extractor free?

Yes. Extraction, all four color formats, every export target, and the WCAG contrast check are free with no signup and no watermark.

Can I pick a single specific color instead of a whole palette?

Yes. You can click any point in the image to sample that exact color as a color picker from image, or let the extractor surface the dominant colors automatically.

What is the difference between HEX, RGB, HSL, and OKLCH?

HEX and RGB describe the same color in different notations; HSL exposes hue, saturation, and lightness for easy tweaking; and OKLCH is a perceptually uniform space that is ideal for generating even shade steps.

Does the image leave my device?

No. The entire process runs client-side in your browser, so your image is never uploaded anywhere.
