I can't find my last comment. Humm....I must not have saved it! Ok, I'll repeat.
Your color combo for 59 is perfect - it draws the reader to it. You really have the emphasis in the right place. In 56 and 59 "PaperFree really jumps out". I like that, especially when I think of the gray background we have on the product pages. I'm also drawn to the graphic on 19. I'm wondering what the 19 graphic on 59 would be like. The lower left curved edge of 19 might fit nicely next to the "R" of "PAPER".
Also, can we experiment with upper and lowercase - Paper .... Free - to see how it looks?
Good work!
