Claim Text:
1. A plurality of asymmetric color-shifting flakes, each comprising: an asymmetric magnetic structure with a first side and a second side, wherein the first side has a magnetic layer, a first spacer layer on the magnetic layer, and a first absorber layer on the first spacer layer; wherein the second side has a non-magnetic reflector layer, a second spacer layer on the non-magnetic reflector layer, and a second absorber layer on the second spacer layer; wherein the magnetic layer is visible on the first side of the asymmetric magnetic structure and the non-magnetic reflector layer is visible on the second side of the asymmetric magnetic structure; wherein the first side of the asymmetric magnetic structure provides a first color-shifting effect on the first side of the asymmetric magnetic structure; and wherein the second side of the asymmetric magnetic structure provides a second color-shifting effect on the second side of the asymmetric magnetic structure.
