There's supposed to be a color scheme throughout a home???
Huh, imagine that.
Do what you want to do, bright cheery colors never hurt anyone.
If all your quilts totally "go" with your color scheme then then what keeps them from blending into oblivion? I want my quilts to stand out. I want them to vary enough that when you enter a room they're what catches the eye rather than the dusty table by them.
