Digital Color Mixing Isn’t Like Paint
Mix red and blue paint and you get purple. Mix red and blue pixels using RGB averaging and you get… #800080. Which is also purple, but the path there is completely different. Digital colors blend additively, not subtractively, and the method you choose changes the result more than most people expect.
This tool offers two blending modes. RGB Average does the math on each channel independently, simple and predictable. HSL Interpolation travels around the hue wheel, which tends to produce more vibrant intermediates. A weight slider lets you shift the blend toward either input color, and you can mix up to 6 colors at once.
The Muddy Color Problem
Here’s something designers learn the hard way: blend a red and a green using RGB averaging and you’ll get an ugly brownish gray. The opposing channel values cancel each other out. It’s mathematically correct but visually awful.
Switch to HSL mode and the same blend travels through the hue wheel, producing a more saturated yellow or orange depending on the path. When your gradient between two complementary colors looks muddy, this is usually why, and switching the interpolation method fixes it.
Practical Applications
Gradient midpoints. Your gradient goes from deep blue to warm orange, but the middle looks washed out. Find the exact midpoint color here, then add it as a third gradient stop to control the transition.
Hover states. You need a color between your primary brand blue and white for a button hover effect. Mix at 30% weight toward white. That’s your hover color, and it’s guaranteed to belong to the same visual family.
Design tokens. Creating a design system and need intermediate shades between your primary and secondary colors? Mix at 25%, 50%, and 75% weights for a set of colors that smoothly bridge the two.
Teaching. The difference between RGB averaging and HSL interpolation is one of those concepts that clicks immediately when you see it side by side. Mix the same two colors with both methods and the difference is obvious.
Weight Slider Mechanics
At 0%, the result is entirely the first color. At 100%, it’s entirely the second. At 50%, equal contribution from both. When mixing more than two colors (up to 6), the slider disappears and all colors contribute equally.
