Crazy Vedauwoo Guide Book

I just got the Robert Kelman guide to Vedauwoo. The colored arrows labeling routes don't make any sense. Help before we go insane!

really, Just go there and use the book, if you can't figure it out, then I feel bad for ya. The formations are quite obvious as are the lines. Plus they are all super short pitches. It's pretty straight forward and the book is all the information you need. Not much gear beta in the book and there shouldn't be, if you can't look up a 50 ft pitch and figure out what to bring, then the Voo might be a bit punishing, Especially if your using that terrible book.

Everything about the guide is fine, we were just like "what's with the color scheme?"
