Violet light has a wavelength between approximately 380 and 435 nanometers. [2] The color's name is derived from the Viola genus of flowers. [3] [4] In the RGB color model used in computer and television screens, violet is produced by mixing red and blue light, with more blue than red.
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.
Hexadecimal 8-bit RGB representations of the main 125 colors. A color in the RGB color model is described by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet ( r, g, b ), each component of which can vary from zero to a defined maximum value.
The typical artists' paint or pigment color wheel includes the blue, red, and yellow primary colors. The corresponding secondary colors are green, orange, and violet or purple. The tertiary colors are green-yellow, yellow-orange, orange-red, red-violet/purple, purple/violet-blue and blue-green.
Subsequently, German and English scientists established in the late 19th century that color perception is best described in terms of a different set of primary colors—red, green and blue-violet ( RGB )—modeled through the additive mixture of three monochromatic lights.
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 complementary primary–secondary combinations are red – cyan, green – magenta, and blue – yellow. In the RGB color model, the light of two complementary colors, such as red and cyan, combined at full intensity, will make white light, since two complementary colors contain light with the full range of the spectrum.
RYB (an abbreviation of red–yellow–blue) is a subtractive color model used in art and applied design in which red, yellow, and blue pigments are considered primary colors. [1] Under traditional color theory, this set of primary colors was advocated by Moses Harris, Michel Eugène Chevreul, Johannes Itten and Josef Albers, and applied by ...
Although the web color "violet" may be called light violet it is technically actually a light magenta, since the red and blue values of the color are equal (which signifies for computer display that this color is a shade of magenta ), and therefore another name for this color is lavender magenta, [18] [19] [20] analogous to the colors lavender ...
Several modern sources place indigo in the electromagnetic spectrum between 420 and 450 nanometers, [1] [24] [25] which lies on the short-wave side of color wheel (RGB) blue, towards (spectral) violet. The correspondence of this definition with colors of actual indigo dyes, though, is disputed.
