Non-dichroic omnidirectional structural color

A process for producing a non-dichroic omnidirectional structural color paint pigment, the process comprising;

• providing an absorbing layer, the absorbing layer being selected from the group consisting of chromium, nickel, carbon, graphite, graphene, titanium, vanadium, aluminum, cobalt, silver, molybdenum, niobium, iron, steel, tungsten and alloys thereof;
• providing a first layer extending over the absorbing layer, the first layer having a first thickness and a first index of refraction;
• providing a second layer extending over the first layer, the second layer having a second thickness and a second index of refraction, the absorbing layer, first layer and second layer reflecting a single narrow band of visible electromagnetic radiation having a reflectance of between 65-80% of incident light waves, a width of less than 200 nanometers and a center wavelength shift of less than 50 nanometers when viewed from angles between 0 and 45 degrees and exposed to a source of broadband electromagnetic radiation.
