By convention, the three primary colors in additive mixing are red, green, and blue. In the absence of color, when no colors are showing, the result is black. If all three primary colors are showing, the result is white. When red and green combine, the result is yellow.
Also, is the color black all colors combined?
A black pigment can, however, result from a combination of several pigments that collectively absorb all colors. If appropriate proportions of three primary pigments are mixed, the result reflects so little light as to be called "black".
Is black all of the colors?
The same theory applies to black and white. Black is not a color; a black object absorbs all the colors of the visible spectrum and reflects none of them to the eyes. The grey area about black: A black object may look black, but, technically, it may still be reflecting some light.
What color has all the colors in it?
Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow. Combining primary colors of light like red, blue, and green creates secondary colors: yellow, cyan, and magenta.
