The wickedly awesome texture is created by choosing to knit certain colors as they appear and purling others. In this case I used Back Light and knit whenever the yarn was pink, orange or yellow and purled whenever it was blue or green. Black was neutral, so if it was in a warm run I knit it and it if was in a cool run I purled it and if it was between a warm and cool run I used it for transition. Have fun! Go crazy!
