Colour’s appear, as if by magic.
I tried a harder subject. This pic started off low res, so although I think I introduced some noise in the suit area, it’s acceptable for what we are trying to do.
This time there is a gradient map, changing the suit colour from brown to red(ish). Most suits are dark, so making each agent’s suit a different colour will be more of a challenge. Perhaps consider making other details coloured and have the suits stay greyscale?
