    en.wikipedia.org/wiki/Visible_spectrum

    The spectrum does not contain all the colors that the human visual system can distinguish. Unsaturated colors such as pink, or purple variations like magenta, for example, are absent because they can only be made from a mix of multiple wavelengths. Colors containing only one wavelength are also called pure colors or spectral colors. [8] [9]

    The human eye's red-to-green and blue-to-yellow values of each one-wavelength visible color [citation needed] Human color sensation is defined by the sensitivity curves (shown here normalized) of the three kinds of cone cells: respectively the short-, medium- and long-wavelength types.

    Birds, however, can see some red wavelengths, although not as far into the light spectrum as humans. [46] It is a myth that the common goldfish is the only animal that can see both infrared and ultraviolet light; [47] their color vision extends into the ultraviolet but not the infrared. [48]

    en.wikipedia.org/wiki/Monochromacy

    Monochromacy (from Greek mono, meaning "one" and chromo, meaning "color") is the ability of organisms to perceive only light intensity without respect to spectral composition. Organisms with monochromacy lack color vision and can only see in shades of grey ranging from black to white. Organisms with monochromacy are called monochromats.

    Chromostereopsis is a visual illusion whereby the impression of depth is conveyed in two-dimensional color images, usually of red–blue or red–green colors, but can also be perceived with red–grey or blue–grey images.

  9. Eigengrau - Wikipedia

    en.wikipedia.org/wiki/Eigengrau

    For example, the night sky looks darker than Eigengrau because of the contrast provided by the stars. Contrast threshold data, collected by Blackwell [5] and plotted by Crumey, shows Eigengrau occurring at adaptation luminances below approximately 10 − 5 cd m −2 (25.08 mag arcsec −2). [6] This is a limiting case of Ricco's law.
