    Underwater vision is the ability to see objects underwater, and this is significantly affected by several factors. Underwater, objects are less visible because of lower levels of natural illumination caused by rapid attenuation of light with distance passed through the water. They are also blurred by scattering of light between the object and ...

    Thus, while the color of the after-image produced by looking at a green surface that is reflecting more "green" (middle-wave) than "red" (long-wave) light is magenta, so is the after–image of the same surface when it reflects more "red" than "green" light (when it is still perceived as green).

    Light and dark spectra—when coloured edges overlap in a light spectrum, green results; when they overlap in a dark spectrum, magenta results. (Click for animation) Since the colour phenomenon relies on the adjacency of light and dark, there are two ways to produce a spectrum: with a light beam in a dark room, and with a dark beam (i.e., a ...

He thus argued that the red–green and blue–yellow cells should be instead called green–magenta, red–cyan and blue–yellow complementary cells. An example of the complementary process can be ...
