Within the CMY color space used in color printing, a range of colors can be achieved by combining the three primary colors.This combination can be thought of as a hue component (which will require a maximum of two primary colors) and a grey component (a mixture of all three, in an appropriate quantity to give the required saturation).
For all additive color models, the absence of all primaries results in black. For practical additive color models, an equal superposition of all primaries results in neutral (gray or white). In the RGB model, an equal mixture of red and green is yellow, an equal mixture of green and blue is cyan and an equal mixture of blue and red is magenta.
Possible lightness values are 15% through 90% in steps of 5% for monochromatic shades of grey (i.e. C = 0%) and 20% through 90% in steps of 10% and additionally 85% and 93%. Chroma values are also mostly confined to steps of 10% or 5%, but with some exceptions, and the maximum value varies.
This is a list of software palettes used by computers. Systems that use a 4-bit or 8-bit pixel depth can display up to 16 or 256 colors simultaneously. Many personal computers in the early 1990s displayed at most 256 different colors, freely selected by software (either by the user or by a program) from their wider hardware's RGB color palette.
James Clerk Maxwell, with his color top that he used for investigation of color vision and additive color. Additive color or additive mixing is a property of a color model that predicts the appearance of colors made by coincident component lights, i.e. the perceived color can be predicted by summing the numeric representations of the component ...
An RG color model is a dichromatic color model represented by red and green primary colors. These can only reproduce a fraction of the colors possible with a trichromatic color space, such as for human color vision. The name of the model comes from the initials of the two primary colors: red and green. The model may be either additive or ...
