English

Subject field(s)
  • Optics

DEF

The primary colours of light, i.e. red, green, and blue, that may be combined in various proportions to produce a wide gamut of colours. When added together, these colours produce white light.

DEF

Three main colour bands each covering about one-third of the visible spectrum (blue, green, and red) which on additive mixing will produce white.

CONT

Red, blue, and green are the colors of the filters used in color-separation photography. Cyan, magenta, and yellow are the colors of the printing inks with which we print color reproductions. Each printing or subtractive color represents two of the additive primaries of light that remain after one of the additive primaries is subtracted or absorbed.

OBS

The additive primaries must not be confused with the subtractive primaries, yellow, magenta, and cyan, which are the colors of our inks for full-color printing.

OBS

In the fields of optics (light and colour theory) and photography, when not otherwise specified, the primary colours are the RGB primaries.
