Mmmmm.... double rainbow. This franken is comprised of the dregs of a bottle of OPI DS Original. Maybe an 1/8 of a bottle. The rest is Wet n Wild black creme,TKB Glamour base, and about 2 straw-spoonfuls of Spectraflair. I love it! You really get the full rainbow effect with the black background. These swatches are two coats of Rainbow Road over one coat WnW black creme.
