This is, actually, not inspired by MGS4. I have had this idea sence back when retail first came out, just MGS4 named it now so I can use that to help illustrate my idea better. Basically, when you use it, it will check the color of the bricks around you, and recolor your character to that color. If there is more than one color that is near you, say you are on a checkered floor, the item will randomly color various body parts the colors that you are near. This sort of thing would be really fun in DMs with the names turned off, and I am almost positive this is possible. I dont really know how to check the color of bricks or anything, but I know the fill-can can check for matching color. I am pretty sure that the way to acheive this item would use the same process.
