It makes me unreasonably happy that FFOOFF is far up the top color list. Apparently it seems to be hard to Google, but for those who don't know, prior to wide spread support for alpha channels, FF00FF was one of the colors commonly used for bitmap transparency. Not exactly a commonly used color and exceptionally obvious when working with a sprite sheet.
Edit: You can probably guess what my banner is set to.
