Hey guys, this is sort of a general sprite art theory question. When working with background and foreground tiles, I often find that I need to make background tiles a lot darker to make it clear what one can walk on and what one can't. Sometimes I want to make a background that is close to white though, say for a very clean plaster wall or painted concrete. I find that I can't actually make it very white because of the ambiguity that occurs between the background and foreground, which makes a lot of my backgrounds look fairly gray. Does anyone have any suggestions for this? I can post some examples if that would help, but I imagine many of you have dealt with this too. Thanks!
