Boy, girl... they only grow up to be what they have been conditioned to be (think, feel, act) from society. I was given a baby quilt when my son was born. They thought I had a girl. The quilt was done in bold pinks and greens. I did not care... my son used that quilt when he was a baby and throughout his childhood. Heck, he still has his baby quilt and he is 25 now (and yes, he is a very masculine adult). loll. That quilt holds a lot of memories for him, and he never cared that it was pink and green. Now, if i had told him that it was for a girl or too girly... he might not ever have looked fondly upon that quilt.
Personally I think that bright, bold colors are more interesting for babies to look at as well as something that is also easily grown into as they get older.
