Color Palette Generator from Image — Free Online Tool (2026)

Extract a Full Color Palette from Any Image

A great color scheme is often already sitting inside an image you love — a photograph, a logo, a piece of artwork, or a screenshot of a design you admire. TooStamply's color palette generator reads that image directly in your browser and pulls out a clean, harmonious set of colors you can drop straight into a real project. There is no signup, no watermark, and nothing is uploaded to a server. In 2026 that combination of privacy and developer-ready export is exactly what most designers and front-end developers are looking for from a color palette generator.

This guide walks through how the extractor works, what you get back, and how to move from a raw image to production code without hand-converting a single HEX value.

How the Color Palette Extractor Works

When you upload an image, TooStamply does not just grab a handful of random pixels. It runs a color quantization step built on k-means clustering, which groups the millions of pixels in your image into a small number of representative color "buckets." Each bucket becomes one swatch in your palette, weighted by how much of the image that color actually covers.

Because the algorithm looks at the true color distribution, the result is a color palette from image input that reflects the mood of the whole picture rather than one bright spot in a corner. When you extract color palette from image data this way, the output feels far more coherent than manually eyedropping colors one at a time.

1. Upload any image (JPG, PNG, SVG, or WebP) by dragging it in or selecting a file.
2. Extract — the color quantization pass identifies the dominant colors and returns them as swatches.
3. Refine — nudge individual colors, drop ones you do not want, or ask for more swatches to widen the range.
4. Export — copy the palette in the exact format your project needs.

If you want a deeper walkthrough of the upload-and-tune flow, the color palette from image page covers it step by step.

What You Get Back for Every Color

This is not just a strip of pretty squares. As a proper color palette extractor, TooStamply gives you real, usable values for each swatch:

OKLCH matters more than people expect. Because it is perceptually uniform, adjusting lightness in OKLCH produces shade steps that actually look evenly spaced to the human eye — which is why the same color space powers the shade scales in our Tailwind color palette generator.

Export to Real Code, Not Just Swatches

The point of a color palette creator is to save you the tedious part: turning colors into the format your framework expects. TooStamply exports every palette to the targets developers actually ship with.

• Tailwind CSS — output for both a v3 tailwind.config.js colors block and a v4 @theme directive.
• CSS custom properties — modern --color-* variables for any stack.
• SCSS variables — Sass $-prefixed variables for older or mixed pipelines.
• Bootstrap — color overrides for a Bootstrap 5 build.
• Flutter — Color constants for Dart/Flutter apps.
• React Native — a JavaScript color object ready to import.

Here is the kind of CSS-variable block you can copy in one click:

:root {
  --color-primary: #3b82f6;
  --color-secondary: #1e293b;
  --color-accent: #f59e0b;
  --color-surface: #f8fafc;
}

And the equivalent for a Tailwind v4 project:

@theme {
  --color-primary: #3b82f6;
  --color-secondary: #1e293b;
  --color-accent: #f59e0b;
}

Built-in WCAG Contrast Checker

A palette that looks good but fails accessibility is a palette you will have to redo. For every color pair, TooStamply calculates the WCAG contrast ratio and tells you whether it passes AA or AAA. That means you can confirm your body text is readable on your background color before you write a single line of markup.

• AA normal text needs a ratio of at least 4.5:1.
• AA large text needs at least 3:1.
• AAA enhanced needs at least 7:1.

The checker shows a clear pass/fail badge for each combination, so accessibility is a decision you make early instead of a bug you find in review.

Live UI Mockup Preview

Colors rarely look the same in a swatch as they do in a real interface. The built-in mockup previews your extracted palette on buttons, cards, headings, and background surfaces, so you can judge how the colors behave together in context. If a bright accent overwhelms everything around it, you will see that before you commit the palette to a design system.

Practical Use Cases

A flexible color palette app earns its place across a lot of workflows:

• Brand and web design — base a whole site theme on a single hero image or logo.
• Photography — build matching themes from your own shots for portfolios and prints.
• Interior and product design — pull a scheme from a room photo or product render.
• Art study — examine the color relationships master painters actually used.
• Marketing — keep colors consistent across slides, social posts, and landing pages.

If you prefer to start from color theory instead of a photo, the color palette generator and the interactive color wheel let you build harmonious color schemes from a single base color.

Frequently Asked Questions

Is the color palette generator really free?

Yes. Every feature — extraction, all export formats, the OKLCH values, and the WCAG contrast checker — is free with no signup and no watermark.

Does my image get uploaded anywhere?

No. The entire extraction runs in your browser using client-side JavaScript. Your image never leaves your device, and closing the tab clears it completely.

How many colors can I extract from one image?

You can generate a compact set of dominant colors or widen the range to capture more nuance. Because the extractor uses color quantization, the swatches always stay representative of the image rather than becoming noisy.

Which export format should I choose?

Match your stack: Tailwind config for Tailwind projects, CSS custom properties for framework-agnostic work, SCSS for Sass pipelines, and Flutter or React Native for native apps.
