How to Mix Two Colors Online and Get the HEX Instantly

To mix two colors online, pick a first and second color in the Color Mixer, drag the ratio slider toward whichever should dominate, and read the blended result as a live swatch with copyable HEX and RGB codes. The blend is computed by interpolating the red, green and blue channels, so the midpoint is a true numerical average of your two colors — and it all happens in your browser with nothing uploaded.

This guide walks through the tool from your first pick to pasting the result into CSS or Figma, plus a couple of shortcuts for common jobs like gradient stops and brand tints.

What "mixing" means digitally

On a screen, mixing two colors means blending their channels. For a 50/50 mix the tool averages the two red values, then the two green values, then the two blue values, and assembles the result. The ratio slider simply weights that average — at 80% toward color one, the output leans heavily on color one's channels. Because this is additive RGB math, the results follow screen rules, not paint rules, which is why a red-and-green midpoint reads as a dull brown rather than a vivid tone.

Step-by-step: blend and copy

1. Set your first color. Use the picker or type a HEX code like #1e88e5.
2. Set your second color. Enter it the same way — for example #ffb300.
3. Drag the ratio slider. Slide toward the color you want to dominate; the live swatch updates as you move.
4. Read and copy. The blended HEX and RGB appear below the swatch — click Copy and paste straight into your stylesheet or design tool.

Common jobs, done fast

Goal	How to do it
Midpoint of two brand colors	Set both, leave the ratio at 50%
Soften a harsh accent	Mix the accent with a neutral gray, ratio toward the neutral
Gradient middle stops	Read the blend at 25%, 50% and 75%
Tint toward white	Mix your color with #ffffff at your chosen ratio
Shade toward black	Mix your color with #000000

Why in-browser and private matters

Every blend is calculated locally in JavaScript, so your colors are never sent to a server, there is no account, and the tool keeps working offline once the page has loaded. That makes it safe for unreleased brand work and fast enough to iterate on dozens of blends without a round-trip.

FAQ

What ratio gives a true midpoint?

50%. At the halfway point the tool averages each channel equally, producing the exact numerical middle between your two colors.

Can I mix more than two colors at once?

The tool blends two colors per operation, but you can chain it: mix the first pair, copy the result, then mix that with a third color to approximate a multi-color blend.

Why doesn't the blend look like paint mixing?

Screens use additive RGB, where combining light adds brightness. Paint is subtractive and trends toward dark. The mixer follows screen rules, so expect brighter, sometimes grayer midpoints than pigment would give.

Do I need the # in my HEX code?

No. Enter it with or without the hash; the tool normalizes valid six-digit HEX either way.
