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.
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. [3]
Additive color mixing: projecting primary color lights on a white surface shows secondary colors where two overlap; the combination of all three primaries in equal intensities makes white. To form a color with RGB, three light beams (one red, one green, and one blue) must be superimposed (for example by emission from a black screen or by ...
Purple haze refers to a state of mind induced by psychedelic drugs, particularly LSD. [86] Wearing purple is a military slang expression in the U.S., Canada and the U.K. for an officer who is serving in a joint assignment with another service, such as an Army officer on assignment to the Navy. The officer is symbolically putting aside his or ...
CIE. Archived June 3, 2005, at the Wayback Machine. 1931 Standard Colorimetric Observer functions between 380 nm and 780 nm (at 5 nm intervals).. One of the first mathematically defined color spaces is the CIE XYZ color space (also known as CIE 1931 color space), created by the International Commission on Illumination in 1931.
And he leaned in with his purple attire, purple guitar and purple piano. After his 2016 death, his estate worked with Pantone to come up with an official Prince purple, dubbed “Love Symbol #1.”

As most definitions of color difference are distances within a color space, the standard means of determining distances is the Euclidean distance.If one presently has an RGB (red, green, blue) tuple and wishes to find the color difference, computationally one of the easiest is to consider R, G, B linear dimensions defining the color space.
