Mixing Paint! With Computers!
summary
Explains why RGB linear interpolation makes blue+yellow gray and why CMYK still doesn’t match paint mixing, then shows a physically based alternative, Kubelka-Munk theory, which predicts reflectance but requires per‑pigment scattering and absorption values and is fiddly to implement; notes Kreta removed its painterly mixer in 2012 and the iPad app Paper experiments with and ultimately rejects K‑M in favor of manual midpoints that interpolate to match users’ expectations.
