We are liking logo #1. As with other logos for other companies that I have, we frequently make changes in color, size and elements to suit our needs. With that said, I would like the art to be layered in three different elements. The "Back2U.org" as one, "Fundraising Made Easy!" as the second and the "arrow-circle" as the third. In other words, we may use any element as a stand-alone item or at least have the ability to strip the "fundraising made easy" and the "arrow-circle" off of the "Back2U.org". Can you do this and does it make sense?
Also try these colors: Blue should be H211 S81 B47 or R23 G69 B119 or L28 A1 B34 or C93 M76 Y23 K10. The orange should be H24 S100 B100 or R255 G102 B0 or L63 A57 B73 or C0 M72 Y94 K0.
