Name: Cotton
Description: This is a new crop for the IC2 Agriculture system, the Cotton that we all know well from t-shirts, underwear, and the history of the American South. The crop is fairly low tier; III or so. When harvested, it drops wool - but only plain cotton will drop white wool! There are other varieties of cotton that can be bred that drop all the other colors of wool, which can be obtained by crossing ordinary white cotton with the appropriately colored flower or other dye plant (I know there's yellow, red, and light blue flowers, a coffee/cocoa plant that will do for brown, and I think a black one as well) for the primary colors, then crossing them with each other for the colors in between (so to get orange you breed together yellow cotton and red cotton). Will make farming colored wool for pixel art or colored floors or whatnot easy on survival and you don't have to get your hands dirty cleaning up after all those sheep.
Recipe: It's a crop. Basic crop, kinda similar to wheat or hops or one of those other flowers, so white cotton probably can be obtained from crossing wheat/wheat and will just look like a variant of wheat. Colored cotton varieties are obtained by crossing white cotton with the appropriate color dye plants and/or with each other.
Edit: Removed colored cotton. We already can farm most dyes, no reason to make it redundant. Still need Green and Blue in the system though to be able to get all the colors from IC2 Agriculture.
