I'm somewhat color challenged and it takes me along time to get the colors to play nice with each other. My DH, on the other hand, can look at the fabrics and make selections that go together perfectly. So when I start a new project I grab every fabric I think will work and then start laying them out. I also rely on the choices made by the designer of the pattern, while I may change the shades; but if a professional did it I'm pretty confident in using their choices. The one thing I wish I could do is break away from my conservative nature and go for brighter colors. Ah well, as long as my friends and family are happy with their gifts then I must be doing something right.
