Abstract
A coloring structure includes a light-reflecting base, a brilliant layer placed on the base, and transparent brilliant units contained in the brilliant layer, each brilliant unit including an alternate lamination of at least two polymers having different refractive indexes, the lamination producing interfered light resulting from reflection and interference of light and transmitted light resulting from transmission of light, each brilliant unit controlling interfered and transmitted lights. The coloring structure is provided with a coloring mechanism for producing at least an interference color resulting from interfered light, a first object color resulting from reflection of transmitted light produced by the base, and a second object color resulting from reflection of incident light produced by the base without striking any brilliant units.
