About the Color Mixer
The Color Mixer blends any two colors into one. Pick a first and second color, then drag the ratio slider to control how much of each goes into the mix — the result is calculated by interpolating the red, green and blue channels and shown as a live swatch with its HEX and RGB codes.
It is perfect for finding a midpoint between two brand colors, softening a harsh accent with a neutral, or generating the in-between steps of a gradient by hand. Every value is copyable with one click so you can paste it straight into CSS, Figma or your design tokens.
All blending math runs 100% locally in your browser. No colors are uploaded, there is no sign-up, and the tool keeps working offline once loaded.
Frequently asked questions
How does mixing two colors work digitally?
Digital color mixing interpolates each channel separately. For a 50/50 blend, the tool averages the red values of both colors, then the green values, then the blue values. A ratio slider simply weights that average toward one color or the other.
Why does mixing red and green make a muddy brown?
In the additive RGB model used by screens, averaging red (255,0,0) and green (0,128,0) lands on a dull yellow-brown, not the vivid result you might expect from paint. Screen mixing follows different rules than physical pigments, so complementary hues tend toward gray or brown at the midpoint.
What is the difference between RGB and paint color mixing?
RGB is additive: combining light adds brightness, so red plus green plus blue makes white. Paint is subtractive: pigments absorb light, so mixing many colors trends toward black. This tool mixes in RGB, matching how colors combine on a screen.
Can I use the mixer to build a gradient?
Yes. Set your two endpoint colors, then read the blend at 25%, 50% and 75% to get evenly spaced middle stops. Dropping those HEX codes into a CSS gradient gives you precise control over the transition.
Is the color mixer free and private?
Completely. It runs entirely in your browser with JavaScript, nothing is uploaded or logged, there is no account, and it works offline after the first load.
