The normal three kinds of light-sensitive photoreceptor cells in the human eye (cone cells) respond most to yellow (long wavelength or L), green (medium or M), and violet (short or S) light (peak wavelengths near 570 nm, 540 nm and 440 nm, respectively [7] ).
Each color code listed is a shorthand for the RGB value. For example, code 609 is equivalent to RGB code 102-0-153 or HEX code #660099. Safest web colors. Designers were encouraged [by whom?] to stick to these 216 "web-safe" colors in their websites because there were a lot of 8-bit color displays when the 216-color palette was developed.
In the CMYK color model used in printing, violet is created with a combination of magenta and cyan pigments, with more magenta than cyan. On the RGB / CMY ( K) color wheel, violet is located between blue and magenta. Violet is closely associated with purple.
The following is a list of colors. A number of the color swatches below are taken from domain-specific naming schemes such as X11 or HTML4. RGB values are given for each swatch because such standards are defined in terms of the sRGB color space.
In the Munsell color system, this color at its maximum chroma of 12 is called Red-Purple, or more specifically Munsell 5RP. Artists' pigments and colored pencils labeled as purple are typically colored the red-violet color. On an RYB color wheel, the so-called red-violet color is the color between red and violet.
The Munsell color system, showing: a circle of hues at value 5 chroma 6; the neutral values from 0 to 10; and the chromas of purple-blue (5PB) at value 5. In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), value ( lightness ), and chroma (color intensity).
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.
1931 CIE chromaticity diagram showing some RGB color spaces as defined by their chromaticity triangles. RGB color spaces are additive colorimetric color spaces specifying part of its absolute color space definition using the RGB color model.
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. The study of colors in general is called color science .
RGB uses additive color mixing, because it describes what kind of light needs to be emitted to produce a given color. RGB stores individual values for red, green and blue. RGBA is RGB with an additional channel, alpha, to indicate transparency. Common color spaces based on the RGB model include sRGB, Adobe RGB, ProPhoto RGB, scRGB, and CIE RGB.
