Color mixer
Blend two colors at any ratio. We show the OKLab blend (perceptually correct) alongside the RGB blend (what most tools do) so you can see the difference.
Why two blends?
Mixing colors in plain RGB looks wrong, especially at the midpoint of a complementary pair. Yellow + blue should give green, the way mixing paint does — but in RGB they average to a muddy gray. The reason is gamma: sRGB values are stored on a curve that doesn't correspond to physical light intensity, so averaging them isn't really averaging anything meaningful.
OKLab is a perceptually-uniform color space designed by Björn Ottosson (2020). Interpolating in OKLab gives results that match what your eye expects: yellow + blue makes green, red + green makes yellow-ish, and the midpoint of any two colors stays vivid instead of collapsing to gray.
