    11I would say that the main problem with GrafX2's interpolation is that it in a very real sense is NOT linear. It interpolates sRGB values as if they were linear, but sRGB itself is definitely not linear (https://en.wikipedia.org/wiki/SRGB#The_sRGB_transfer_.28gamma.29_function has a nice graph). The result is mathematically nonsensical, but sometimes convenient (since it often produces more distinct shades than a linear interpolation).
