What is Image Color Palette?
Design systems often start with 'pick colors from this reference image'. Instead of eyeballing swatches, this tool downscales the image, samples pixels, and runs k-means clustering to find the true dominant colors — weighted by how much of the image each color covers. You get the swatches with HEX/RGB/HSL, plus ready-to-paste Tailwind config and CSS custom properties.

Tips & Best Practices
- ▸6 is a good default — enough variety, still visually manageable.
- ▸The tool ignores fully transparent pixels but includes semi-transparent ones (α ≥ 50%).
- ▸For designer-friendly palettes, use 4-6 colors. For data-visualization palettes, 8-12 is more useful.
Frequently Asked Questions
How does it pick the colors?
The tool samples a downscaled version of your image (up to about 4,000 pixels), then runs k-means clustering with k-means++ initialization for the number of colors you asked for. Bigger clusters — dominant colors — show first.
Can I use these colors in my design system?
Yes. Below the swatches you get ready-to-paste Tailwind config and CSS custom properties (brand1..brandN), so you can drop them directly into your theme.
Is my image uploaded?
No. All sampling and clustering happens in your browser.
