Violet is closely associated with purple. 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, [5] [6] some of which humans perceive as similar to violet.
The complement of any primary color can be made by combining the two other primary colors. For example, to achieve the complement of yellow (a primary color) one could combine red and blue. The result would be purple, which appears directly across from yellow on the color wheel.
Color theory, or more specifically traditional color theory, is the historical body of knowledge describing the behavior of colors, namely in color mixing, color contrast effects, color harmony, color schemes and color symbolism. Modern color theory is generally referred to as Color science.
According to some speakers of English, purple is simply a combination, in various proportions, of two primary colors, red and blue. [48] According to other speakers of English, the same range of colors is called violet.
Violet refers to any colour perceptually evoked by light with a predominant wavelength of roughly 380–450 nm. Tones of violet tending towards the blue are called indigo. Purple colors are colors that are various blends of violet or blue light with red light.

The theory of color includes the color complements; color balance; and classification of primary colors (traditionally red, yellow, blue), secondary colors (traditionally orange, green, purple) and tertiary colors.
Crayola crayons set up a color naming system similar to that used in the Munsell Color Wheel, except that violet instead of purple was used as the secondary color on the color wheel between red and blue.
The tertiary color on the HSV color wheel (also known as the RGB color wheel) precisely halfway between blue and magenta is called color wheel violet. This tone of violet—an approximation of the color violet at about 417 nanometers as plotted on the CIE chromaticity diagram—is shown at right.
In color theory, color harmony refers to the property that certain aesthetically pleasing color combinations have. These combinations create pleasing contrasts and consonances that are said to be harmonious.
In color theory, a color scheme is a combination of 2 or more colors used in aesthetic or practical design. Aesthetic color schemes are used to create style and appeal. Colors that create a harmonious feeling when viewed together are often used together in aesthetic color schemes.
