Why These Colors are Not in a Rainbow
- Light Composition: Rainbow colors result from the splitting of white light into its constituent spectral colors. The colors listed above do not form part of this spectrum.
- Pigment vs. Light: Many of these colors, such as brown and pink, are created by mixing pigments, rather than being a pure spectral color of light.
- Absence or Combination: Colors like black and white are the absence and combination of all colors, respectively, rather than a specific wavelength. Metallic colors are composed of pigments and also the result of light reflection on metallic surfaces.
