Change GUI background colors.

Your Module Selection GUI icons are nice, but the 5 gui background colors are garish and uncomplimentary. The white text on the fuchsia background is particularly difficult to read. It would look more modern if you would simply replace all five with a light shade of gray with a hover color of white. If you are going to use colors, select a nice pallet. Lots of good examples if you google "beautiful 5 color pallets."
