Question. Is there a way to only colorize part of an image? Like being able to apply a color to everything in an image that is pure grayscale and leave everything else that already has color information alone? I think that would be the ideal setup.
Certainly its doable, just check if the RGB values at a pixel are all equal and if so color it while leaving other pixels alone. The downside is that you only get to use one color on it which I don't think is enough diversity to show the myriad materials people expect, though more layers might compensate.
