I recently made a color palette (six colors I think) and went through the wiki's styling verifying it. Doing so is a great way to keep the wiki's base simplified. You don't need a dozen colors to have a nice looking wiki but you wanna stay consistent overall.

Definitely don't modify everything you can. It doesn't look good, it irritates some (don't touch the mouse icon), and is hard to maintain.
