I replace all of certain color with something like bright red, then replace it with the new color, which makes it easier to keep track of what you've replaced, then repeat. And what do you think about this house, I obviously haven't inserted it (because I don't want to spend an hour recoloring it just to decide that I don't want to use it), just copy & pasted it onto a-map with paint becuase I wanted to see how it would look. Do you think it clashes with the other tiles? (And the tile is private)
