Abstract
A coloring structure includes a surface layer placed on a base with light transparency and containing transparent brilliant members, each brilliant member including an alternate lamination of at least two polymers having different refractive indexes, and controlling interfered light resulting from reflection and interference produced by the alternate lamination and transmitted light other than interfered light and passing through the alternate lamination. The brilliant members may dispersedly be contained in the base.
