I will use any color under the sun in my quilts if I think it belongs there. I love the contrast of blue & purple against yellow - they are opposite on the color wheel and I think they are striking used together. I do not like orange, brown (boring), mustard yellow or dirty gold. But I made a nice quilt with all those colors in it. I fell in love with a particular floral border fabric and I bought other fabrics in that line and make my Pink Lemonade quilt with them. Somehow I didn't mind working with those oranges/golds/browns. Usually I only use browns in men's quilts.
