If you don't like it, don't use it. Blue is a very popular color for interior wall paint in our area right now, but my mom just absolutely detests the color & it wouldn't matter if every other house on the street was painted top to bottom blue, she'd never add a single blue wall to her house.
I personally like mauve. It looks fresher against a bright white background rather than some of the dustier or creamier backgrounds when it was originally used. Same thing with that beautiful bright lemon yellow -- it gives it a different look than cream/beige. I also like it with that modern grey with just a hint of beige in it. But they're your quilts & you get to decide. I'm sure they'll be just as lovely with or without the mauve in them.
