All of the guys in my family love color! The more vibrant the better. My husband has surprised me a few times by being very ( taken) by a quilt that was very* floral* but the design/layout was what drew him in, not the fabrics. I use my scraps in what ever way seems to work best for the pattern. My sons always loved the brightest, most colorful quilts I made, my daughter is more ( muted) in her pallet preferences. My niece recently got married, the men in the wedding party wore charcoal gray suits with light watermelon pink shirts.... They were Very Sharp looking, not a girly looking one in the bunch! You might not want your baby boy in pink sleepers, but beyond that, boys love vibrant design and color!
