I've long been a fan of Margie Deeb's amazing books about color for beaders and now I've learned that she's got FREE articles (and podcasts...if you are a pod-type person) on color on her website!
She's also got a great .pdf download on Pantone's Spring/Summer 2009 color forecast as it relates to beads and jewelrymaking. It's not free, but $9.50 seems pretty reasonable to me. Heck, if you are color-challenged like me, it's practically a life-saving bargain!
So, go forth and color!
