LOL! I've always loved bright colors, and never was held too much to what the 'in' colors were because I sewed for myself, as long as I could find fabric that I liked. Purple and green was a combo I always liked as well as the turquoise, pink and purple combo. Red and purple are my two favorite colors right now.
I never wore black much, but when I had my colors done, it showed that black is a good color for me. I prefer navy if I'm gonna wear something dark, but I do have a nice black sweater set that I can wear for at least 2 seasons up here!
I like purple and green together too! Very nice. And I'm like you, I find that the best part about sewing is getting the stuff I like in the colors and prints that I like.
