First of all, congrats on finding a woman who would be interested in archery and the outdoors.
I wish I did. Mine camps with me, but doesn't hunt, has no desire to shoot a bow, and will only shoot a gun if its a 22.

If your girlfriend doesn't plan to hunt with the bow, who cares what color it is? It's her bow , right?
If she gets her bow exactly like she wants it, she'll probably be more interested in shooting it.
Just make sure she understands that if she wants to hunt later on, she could end up needing a second bow if she gets the funky one now.

Cangrats again.
What are you doing posting on here?!
Get her to the archery store, and flingin' some arrows.
