I have a complete collection of d20 Modern books and had noticed on the on the hardbacks that most of the logoes on the spine are black and white and are pointed from left to right on the bottom of the spine, except for the d20 Weapons Locker which is pointed down and d20 Darkmatter which is in color (and much smaller than the rest, in the same style as the Star Wars books).
