When I 1st started quilting I was afraid to use color so stuck with white or off-white. Now since advancing in my hobby as I call it, I've tried to jump out of my comfort zone and tried new things. My 1st was the red/black/grey quilt, my avatar...I quilted using red thread with a black backing so it really showed up. I was amazed with how the thread sparked up the back as well as the front. Now when I get ready to quilt I think about the back as well as the front how I want it to show. Just finished a lap quilt with many brights and darks fabrics and decided to try grey as suggested here on the board many times past. I really like it. The back was a peach solid fabric I wanted to get used up and it looked great with the grey thread. I like trying new things these days. Don't think I've quilted with a white or off-white in quite some time now.
