Boys like bright colors too. I have 3 grandsons and they all like a full range of colors. I make PL quilts too I make quilts with all colors and even toss in a few pastels, pink, purple, light greens and blues from time to time to add interest. It all depends on the pattern. I tend to lean to scraps from my green bin and my blue bin which is everything from lights to deep colors. I have made several in the brown/gold/tan color way. To keep the blues or green for that matter a splash of yellow or turquoise makes them fun and keeps the quilt creation interesting for me too. I do try to avoid large floral prints. But use lots of animal prints, black and white, sports and the like. All just stuff from stash.
