i'm working on this layout www.myspacelayoutninja.net and i want the images in the far right sidebar (the 125x125's under the firefox ad) to appear desaturated, and then when you mouse over them the color comes back. is there any way to do that? also, i want to change the color of the links in the "categories" widget in the first sidebar (but none of the other links) but i can't find it, anyone know where they are?
