more new-to-me yarn

Here's another yarn I found in my LYS. Regia sock yarn (approx. 420 m/100g ball. 70% wool, 25% polyamide, 5% acrylic). It's made by Coats.
Don't the colors of this one just make you think of a gorgeous peacock with his tail feathers regally spread? I need to design something using a stitch that mimics the peacock's tail feathers. Hmmmmm...

Here it is in their blue color scheme. The colors are so rich. Wouldn't it look fabulous in a lacy shawl to drape around your shoulders?
