Robin, I'm a solid colour man myself. I have a couple of summer short sleeves that have patterns...one or two...but for the most part, I eschew patterns, stripes, etc.
I also like only autumn colours...greens, browns, reds, yellows, and oranges. Aside from a couple of pairs of blue jeans...I have almost no blue. I have one black shirt that my brother sent me one Christmas, but aside from it and my tux, I never wear black either. I hate the way it has become the uniform colour of the so-called hip these days. So many people wear it who just do not look good in it.
