Additive Mixture of Color
Unlike the subtractive mixture of color, in the additive mixture of color, a color is generated by adding (additive) colored light. If the three basic colors blue, red and green are mixed evenly, the tone is white. An example of use are monitors and screens (for example TV, smartphone or computer screens), where an individual color is created by a combination of the three basic colors. In practice, the RGB color model is based on the additive mixture of colors.
Autotypical Mixture of Color
The autotypical mixture of color is a combination of the additive and the subtractive mixture of color. It is used in the area of printing (for example for large posters). Ink dots are printed side by side so that they partly overlap and that they are partly on white ground. When there is enough distance between the spectator and the printing, there is an additive mixture of color, because the ink dots are not longer perceived as individual points because of there small size and on the other hand there is a subtractive mixture of color at the overlapping points. In summary, the impression of a special color is generated by an additive mixture of color as well as a subtractive mixture of color and the non-printed white areas.
Apart from the saturation and the hue, the blackness stage or the lightness is one of three properties, people sense as fundamental when perceiving colors. The HSV color model is based on these three properties. The blackness value is the parameter for the total energy content or the maximum amplitude of light. The smaller the value, so pure seems the color. If this value is zero, each color is black. The opposite of the blackness value is the lightness. In the HSV color model, the blackness value or the lightness is the V (value), so that this value can be lookalike in the program pipette very well.
