Mate, you have no idea. You can change every color on the interface. Seriously.
Boot up windows 98 on a VM and look into the customization options. You can change font type, size, color of titles, menu bars, scroll bars... Seriously.
The same customization options are on windows XP and iirc 7 too, on the classic interface option. I'm just not sure if everything is still in them.
