Blend two colors together and generate gradient steps between them.
A color mixer blends two colors at a chosen ratio and reports the result. HexColor Pro interpolates channel by channel — a 50/50 mix lands halfway in RGB — and shows the intermediate steps, which makes it easy to build a smooth ramp between two brand colors.
By interpolating each channel: mixing two colors at 50% gives ((R1+R2)/2, (G1+G2)/2, (B1+B2)/2) for an RGB mix. Mixing in a perceptual space such as OKLab instead produces a result closer to how the blend appears to the eye.
RGB mixing passes through desaturated midpoints, so mixing complementary hues lands near grey. That is a property of the color model, not a bug; add a third color, or mix in a perceptual space to keep chroma.
Light is additive: red plus green gives yellow. Paint is subtractive: red plus green gives a dark brown. Screens mix light, so an RGB mixer follows the additive rule.
