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 colors. Modern formulations of Grassmann's laws describe the additivity in the color perception of light mixtures in terms of algebraic equations. Additive color predicts perception and not any sort of change in the photons of light themselves. These predictions are only applicable in the limited scope of color matching experiments where viewers match small patches of uniform color isolated against a gray or black background.
Additive color models are applied in the design and testing of electronic displays that are used to render realistic images containing diverse sets of color using phosphors that emit light of a limited set of primary colors. Examination with a sufficiently powerful magnifying lens will reveal that each pixel in CRT, LCD, and most other types of color video displays is composed of red, green, and blue light-emitting phosphors which appear as a variety of single colors when viewed from a normal distance.
Additive color, alone, does not predict the appearance of mixtures of printed color inks, dye layers in color photographs on film, or paint mixtures. Instead, subtractive color is used to model the appearance of pigments or dyes, such as those in paints and inks.
The combination of two of the common three additive primary colors in equal proportions produces an additive secondary color—cyan, magenta or yellow. Additive color is also used to predict colors from overlapping projected colored lights often used in theatrical lighting for plays, concerts, circus shows, and night clubs.
The full gamut of color available in any additive color system is defined by all the possible combinations of all the possible luminosities of each primary color in that system. In chromaticity space, a gamut is a plane convex polygon with corners at the primaries. For three primaries, it is a triangle.

Helmholtz distinguished between additive and subtractive trichromatic color theories. Additive theories concern optical combinations of colored light sources and are usually modelled on RGB while subtractive theories model pigment mixing and are usually modelled on RYB or CMY. What is the physical basis of this distinction?
Jun 24, 2019 · Color gamut means, that the effectiveness of a color system is best measured by the number of colors that can be created by mixing the primary colors. This set of the colors is the color gamut. There are two main systems: additive, this is where we use red, green and blue. subtractive, this is where we use yellow, green and magenta
The curved edge of this gamut representation are the monochromatic colors. These are the toughest to reproduce in additive color synthesis: you can only produce a monochromatic color by producing its exact peak spectrum. You could consider adding a 4th and 5th primary color to an additive color reproduction system (e.g, an RGBCY monitor).
Aug 30, 2018 · Depending on their ranges, they may be re-encodings of the RGB color space (or coincide with re-encodings of RGB on parts of their domains), but some color spaces use separate approaches to color perception (i.e. they may be additive, like RGB, subtractive, like CMYK, or a nonlinear re-encoding of color, like XYZ or HSV).
Furthermore, LMS tristimulus values for pure spectral colors would, in any normal trichromatic additive color space, e. g. the RGB color spaces, imply negative values for at least one of the three primaries because the chromaticity would be outside the color triangle defined by …
Jul 2, 2018 · Related: Why is there a difference between additive and subtractive trichromatic color theories? RGB is additive color and CMY(K) is subtractive. If you built an electronic screen with CMY subpixels, you'd be able to mix colors additively. Cyan + Magenta = Blue, Cyan + Yellow = green, and Magenta + Yellow = Red.
Jul 30, 2016 · One specific wavelength always creates one color, but the same color can be created by many possible combinations of physical wavelengths. For the sake of shortness I now define the part with the shortest wavelength as "blue" light, the part with the longest wavelength as "red" light and the middle part as "green" light.
You are confusing additive and subtractive colour mixing. If you mix paints together you should get black, not white. In additive mixing (as used in TVs and monitors), you create light, which is then mixed. When you mix the three primary colours (red, green and blue), you produce white.
Sep 18, 2024 · For a green metal, an alloy of silver and gold is also sometimes called "green gold" and has a color described as green-yellow or greenish-yellow. Image source: Wikipedia. For a blue metal, there is osmium. On the photo, you can clearly see osmium's blue color in contrast to the coin's plain silver hue. Source: luciteria.com
In additive color mixing (light), black is zero visible light. In subtractive color mixing (pigments, filters), black is a pigment or combination that reflects or refracts zero light. So, I think that's your answer; if there were absolutely zero EM spectra, you would call it "black".
