Magenta is variously defined as a purplish-red, reddish-purple, or a mauvish–crimson color. On color wheels of the RGB and CMY color models, it is located midway between red and blue, opposite green. Complements of magenta are evoked by light having a spectrum dominated by energy with a wavelength of roughly 500–530 nm.
The human eye's red-to-green and blue-to-yellow values of each one-wavelength visible color [citation needed] Human color sensation is defined by the sensitivity curves (shown here normalized) of the three kinds of cone cells: respectively the short-, medium- and long-wavelength types.
Vermilion is not one specific hue; mercuric sulfides make a range of warm hues, from bright orange-red to a duller reddish-purple that resembles fresh liver. Differences in hue are caused by the size of the ground particles of pigment. Larger crystals produce duller and less orange hues.
In order for all the colors to be spaced uniformly, it was found necessary to use a color wheel with five, non-arbitrary, equally spaced primary colors: red, yellow, green, blue, and purple. The color of the sample is the most chromatic (colorful) red in the sRGB gamut that falls in the hue of 5R (primary red) in the Munsell color space.
English has 11 basic color terms: black, white, red, green, yellow, blue, brown, orange, pink, purple, and gray; other languages have between 2 and 12. All other colors are considered by most speakers of that language to be variants of these basic color terms.
Blue–red contrast demonstrating depth perception effects 3 Layers of depths "Rivers, Valleys & Mountains". Chromostereopsis is a visual illusion whereby the impression of depth is conveyed in two-dimensional color images, usually of red–blue or red–green colors, but can also be perceived with red–grey or blue–grey images.
Red, green and blue lights, representing the three basic additive primary colors of the RGB color system, red, green, and blue. Magenta light is composed of equal amounts of red and blue light. Magenta, shown at the right, is one of the three secondary colors in the RGB color model, used to make all the colors on computer and television ...
Used as a dye, the colour shifts from blue (peak absorption at 590 nm, which is yellow-orange) to reddish-purple (peak absorption at 520 nm, which is green). [22] It is believed that the intensity of the purple hue improved rather than faded as the dyed cloth aged. Vitruvius mentions the production of Tyrian purple from shellfish. [23]
