Claim 10:
11. The structure of claim 1, wherein when measured according to the CIE 1976 color space under a given illumination condition at a first observation angle of about −15 to 180 degrees or about or about −15 degrees and +60 degrees, the optical element has a first color measurement having coordinates L1* and a1* and b1* as measured from the first section of the optical element, and optical element has a second color measurement having coordinates L2* and a2* and b2* as measured from the second section of the optical element, where ΔE*ab=[(L1*−L2*)2+(a1*−a2*)2+(b1*−b2*)2]1/2, wherein the ΔE*ab between the first color measurement and the second color measurement is greater than about 3, then the first structural color and the second structural color are different.
