As mentioned, osage will change color--a lot over the years, so pick a companion wood that will go well with it then. Or as someone mentioned, go with a wood like yellow heart that will stay yellow if that's what you like. I saw a bow Ben Graham of Hummingbird bows built for a friend of mine who liked the real yellow look of fresh osage and wanted it to stay that way. Ben dyed birdseye maple lams the same color as freshly cut osage and it made a strikingly pretty bow which still looks that way after several years. Lots of people prefer the osage after it ages and develops the dark honey color, but if you like the real yellow look just remember it won't stay that way.
