- Color Mixes (experimental)
-
Color mixer is an experimental feature using Mixbox: Pigment-Based Color Mixing. (Mixing within the sRGB gamut, assuming the colors were opaque colors.)Color mixer is an experimental feature using the paints' spectral curves, measured on masstone to predict the mixing path, assuming the paints were opaque.
