use any color you like! When I look any pattern I never ever pay attention to the color of most patterns. I tend to choose whatever strikes my fancy

Just be sure the yarn you choose is the same weight that the patterns calls for or at least make sure the yarn is all the same weight, if you are using more than one color. If you fall in love with a fatter or skinnier yarn than the pattern calls for, try a bigger or smaller hook and ALWAYS make a gauge swatch. I hope this helps. I can't wait to see it when you're done!
