You aren't alone! I do not like grey at all. I think it's "cold."
Our older daughter will be getting married this summer, and is not a fan of "traditional" quilts. Their bedroom is grey with burgundy accents. I've purchased a several cuts of grey, a couple of burgundies and am going to ... Do something with it! Honestly, I think something like the Jelly Roll Race quilt would be her taste! So varying strips of grey, with occasional blocks or HST's of burgundy, may be what ends up coming together. It'd certainly be easy.
