In optics, violet is a spectral color (referring to the color of different single wavelengths of light), whereas purple is the color of various combinations of red and blue (or violet) light, some of which humans perceive as similar to violet.
In the traditional RYB color model, the complementary color pairs are red – green, yellow – purple, and blue – orange. Opponent process theory suggests that the most contrasting color pairs are red–green and blue–yellow. The black - white color pair is common to all the above theories.
According to some speakers of English, purple is simply a combination, in various proportions, of two primary colors, red and blue. According to other speakers of English, the same range of colors is called violet.
The primaries red, green, and blue combine pairwise to produce the additive secondaries cyan, magenta, and yellow. Combining all three primaries (center) produces white. Additive mixing combines two or more colors into a mixture with brightness equal to the sum of the components' brightnesses.
This is a list of flags of states, territories, former, and other geographic entities (plus a few non-geographic flags) sorted by their combinations of dominant colors. Flags emblazoned with seals , coats of arms , and other multicolored emblems are sorted only by their color fields.

A secondary color is a color made by mixing two primary colors of a given color model in even proportions. Combining two secondary colors in the same manner produces a tertiary color. Secondary colors are special in traditional color theory, but have no special meaning in color science .
The color scheme of François d'Aguilon, where the two simple colors of white (albus) and black (niger) are mixed to the "noble" colors of yellow (flavus), red (rubeus), and blue (caeruleus). Orange (aureus), purple (purpureus), and green (viridis) are each combinations of two noble colors. Light and color vision
Even among many modern speakers within the English-speaking world there is confusion about the terms purple and violet. The blue-dominated spectral color beyond blue is referred to as purple by many speakers in the United States, but this color is called violet by many speakers in the United Kingdom.
This model was used for printing by Jacob Christoph Le Blon in 1725 and called it Coloritto or harmony of colouring, stating that the primitive (primary) colors are yellow, red and blue, while the secondary are orange, green and purple or violet.
Red, yellow, and blue are the primary colors of the RYB color "wheel". The secondary colors, violet (or purple), orange, and green (VOG) make up another triad, conceptually formed by mixing equal amounts of red and blue, red and yellow, and blue and yellow, respectively.
