Scanners. Red, green, and blue light that, together, produce white light. These are the primary colours of light from which all other colours can be made.
(n) The three primary colors: red, green, and blue. Color systems use these primaries in differing amounts, working on the principle of adding spectral wavelengths to the light energy to create new colors. This system is used in lighting and computer display graphics. The complementary colors are the subtractive primaries: cyan, magenta, and yellow.
Red, green and blue light. When all three additive primaries are combined at 100% intensity, white light is produced. When these three are combined at varying intensities, a gamut of different colors is produced. Combining two primaries at 100% produces a subtractive primary, either cyan, magenta, or yellow. 100% red + 100% green = yellow; 100% red + 100% blue = magenta; 100% green + 100% blue = cyan See subtractive primaries.
