When I first started lampworking and selling my beads in jewelry, many of my customers commented about the amazing color combinations in my beads.  I always have a few journals going where I write and sketch ideas for future beads.  When I shop I jot down color combinations from clothes, fabrics, and household goods.  Anything that has two or more colors can be a springboard for a bead.  Sometimes I layer clothes on their hangers to experiment with color combinations.  When I am really stumped I use the new colors for each season on the Pantone list.  Be adventurous and experiment with a new color combo the next time you create beads!
