About this tool
Color Mixer is a free, in-browser tool that blends two colors at an adjustable ratio and returns the resulting hex code. Pick a start color and an end color with the native color pickers, then drag the ratio slider from 0 to 100 percent to set how far the mix travels from the first color toward the second.
The blend is computed by interpolating each RGB channel linearly: at 0% the result equals the first color, at 100% it equals the second, and 50% is the exact midpoint. Values are calculated in 8-bit sRGB, rounded to whole channel levels, and shown live as both a large preview swatch and a copyable hex string as you move the slider or change either color.
Everything runs on your device — no uploads, no accounts, no tracking — and it works offline once the page has loaded. Use it to find a halfway tone between two brand colors, generate an intermediate step for a gradient, or preview what two colors produce when combined.
