Feathered Oil Slick Earrings

I really liked the colour combination of the oil slick earrings I posted yesterday, so I tried the same colours again but this time I reversed the bottom and middle layers. I also dragged a needle tool through the oil slick stripes to create a feathered look. And this is the result. Hmmm.... quite different! It's interesting how the placement of colour can deceive the eye.
