I believe those colors will work together as when my parents built their house when we where all kids still at home we where able to pick out the colors for our bedrooms. My sister went with deep purples and pinks with no lighter colors and it look wonderful. She also had black walls!! Please note we had our rooms in the basement with just two little windows per room and with all these dark rich colors it still looked wonderful and bright.
I also had a quilt my grandmother made me when I was about six, and I had picked out my own colors as well and I will say now the colors don't match the best, but at the time I thought it was the best thing ever as I was able to pick out what I wanted and after watching my grandma create such beautiful quilts, she used my fabrics. Looking back after this quilt was made and my grandma used what I had picked it really sparked my urge to learn how to sew and create things myself. As if grandma would use it, I knew it had to be good. Hope this helps.
