I know exactly what you mean about the colors, I go through phases too. I think I'm coming out of a sea-glass bluish-green phase and into a brown phase at the moment...
Red Rooster and Benartex are manufacturers, not designers, but I think I know what you mean. I like a lot of Robyn Pandolph fabrics, they're very feminine, she designs for RJR. I also like Fig Tree, which is manufactured by Moda. Fig Tree designs are pretty and the colors are fresh.
