I'd say you're addicted to purple, but then so am I, purple and teal are my favorite colors, but I've made many quilts not in that colorway and have survived with it not being purple. That's a lovely rail fence, love the purples that you chose. Every once in a while I stretch myself and do something in different colors and the quilt police do not knock down my door, so I guess that's all right. I once made a quilt for a friend. She had sewn strips of all her scrap fabric and then told me she wanted rows of red in between. My litany while sewing the quilt was "red is a neutral - red is a neutral" and got through it. Surprisingly, both my son and husband liked the quilt and the lady loved it, so no harm done. It did teach me to branch out into other colorways though, so I'm not just a teal and purple gal all the time. It doesn't hurt to step out of our safety zone from time to time.
