Fortuna, the Roman goddess of fortune and the personification of luck. Her watercolor counterpart is best described as a double rainbow. The colorshift and undertone itself hit nearly all the colors of the rainbow: pink, orange, yellow, green, blue, purple. The second rainbow comes in the form of the added holographic flakes. The holographic effect is notoriously difficult to capture on camera, but if you've seen the paint mixing video, you know it's there, and it's intense.
