Coated with first color and complementary second color

Abstract

Method of manufacturing a colored product, which includes obtaining a first colored covering material, where the first colored covering material is a first covering material coated with a first coating, where the first coating has a first color, where the first color has a first wavelength, where the first wavelength is 400 nm to 620 nm; measuring the first wavelength of the first color; determining a second wavelength of a second color, where the determining includes calculating the second wavelength by multiplying the first wavelength by a first phi factor, where the first phi factor is a product of n times φ, where n is 0.1 to 100, where φ is 1.618±ε, where ε is 0 to 1, where the second wavelength is 585 nm to 800 nm; obtaining a second covering material, and a second coating having the second color; coating the second covering material with the second coating, to form a second colored covering material; and applying the first colored covering material and the second colored covering material to a product, to form the colored product.
