Match an existing color across HEX, RGB, and HSL, and build a palette around it.

What is the Color Matcher and How Does It Work?
The Color Matcher helps you identify and work with a color you already have - from a screenshot, a brand guide, or a swatch - by matching it across HEX, RGB, and HSL formats, checking how it performs for accessibility contrast, and generating a complementary palette built around it.
Once you enter a color in any format, the matcher converts it to the other two representations and generates a harmonized palette (complementary, analogous, triadic) plus a tint/shade scale, so you can match that exact color across design tools, code, and documentation.
Entering the brand HEX code instantly gives you the RGB and HSL equivalents needed for other tools, plus complementary and analogous colors to pair with it.
Any starting format works - the matcher converts it and keeps every other format in sync.
Common Real-World Use Cases
Enter a HEX or RGB value copied from an image, screenshot, or existing site and get every other format you need.
Confirm a color used elsewhere matches your official brand HEX code exactly across formats.
Start from a color you already have and generate a complementary or triadic palette to design around it.
How This Compares
Both use the same underlying workspace. This page is for when you're starting from a color you already have - copied from a screenshot, brand guide, or another site - and want its equivalents plus a palette built around it. Color Picker is better when you're exploring or don't have a specific starting color yet.
- 1Enter the color you want to match as a HEX code, or use the RGB or HSL sliders.
- 2Review the matched values in all three formats.
- 3Scroll down to see the generated complementary, analogous, and triadic palette, plus tints and shades.
- 4Copy whichever format or generated swatch you need.
- •If you only have a color visually (like from a photo), use your OS screenshot tool or a browser color-picker extension to grab the HEX value first, then paste it in here to match it.
- •The generated palette updates instantly whenever you change the matched color, so it always stays in sync with what you entered.
