Complements of yellow have a dominant wavelength in the range 380 to 480 nm. The green lines show several possible pairs of complementary colors with respect to different blackbody color temperature neutrals, illustrated by the "Planckian locus". In Color theory, the Planckian locus is generally the path or ''locus'' that the color of a Black body would take ina particular Color space Three examples are shown: a 580 nm yellow is complementary to a 435 nm indigo with respect to a 2800 K white; a 580 nm yellow is complementary to a 480 nm blue with respect to a 5000 K white; and a 575 nm yellow is complementary to an extreme violet with respect to a 3600 K white.

Etymology and definitions

The word yellow comes from the Old English geolu, or geolwe which derived from the Proto-Germanic word gelwaz. Proto-Germanic, or Common Germanic, is the hypothetical common ancestor ( Proto-language) of all the Germanic languages such as modern English ^[4] The oldest known usage of this word in English is in the Old English poem Beowulf, in a description of a shield made of wood from a yew tree. Beowulf is an Old English Heroic epic poem of anonymous authorship dating as recorded in the Nowell Codex manuscript from between ^[5] In the English language, yellow is used to describe objects having the color between green and orange in the visible light spectrum (gold, egg yolks, sunflowers, etc. Gold (ˈɡoʊld is a Chemical element with the symbol Au (from its Latin name aurum) and Atomic number 79 ). The color is associated with age and aging, both with people and objects (i. e. yellowed-paper). Ethnographically, the term yellow has also been used as a slang term for both oriental persons and light-skinned African-Americans. The term is associated at times with jealousy, as well as cowardliness. Lastly, it is associated with sensational journalistic practices, or yellow journalism, and resistance to militant trade unions. ^[5]

Complements of yellow

Hunt^[6] defines that "two colors are complementary when it is possible to reproduce the tristimulus values of a specified achromatic stimulus by an additive mixture of these two stimuli. " That is, when two colored lights can be mixed to match a specified white (achromatic, non-colored) light, the colors of those two lights are complementary. This definition, however, does not constrain what version of white will be specified. In the nineteenth century, the scientists Grassmann and Helmholtz did experiments in which they concluded that finding a good complement for spectral yellow was difficult, but that the result was indigo, that is, a wavelength that today's color scientists would call violet. Hermann Günther Grassmann ( April 15, 1809, Stettin ( Szczecin) &ndash September 26, 1877, Stettin) was a Indigo is the Color on the Electromagnetic spectrum between about 420 and 450 nm in Wavelength, placing it between Blue and violet As the name of a color violet (named after the flower violet) is used in two senses first referring to the color of Light at the short- Wavelength Helmholtz says "Yellow and indigo blue" are complements. ^[7] Grassman reconstructs Newton's category boundaries in terms of wavelengths and says "This indigo therefore falls within the limits of color between which, according to Helmholtz, the complementary colors of yellow lie. "^[8] Newton's own color circle has yellow directly opposite the boundary between indigo and violet. These results, that the complement of yellow is a wavelength shorter than 450 nm, are derivable from the modern CIE 1931 system of colorimetry if it is assumed that the yellow is about 580 nm or shorter wavelength, and the specified white is the color of a blackbody radiator of temperature 2800 K or lower (that is, the white of an ordinary incandescent light bulb). In the study of the perception of Color, one of the first mathematically defined Color spaces was the CIE 1931 XYZ color space (also known as CIE 1931 color space The kelvin (symbol K) is a unit increment of Temperature and is one of the seven SI base units The Kelvin scale is a thermodynamic More typically, with a daylight-colored or around 5000 to 6000 K white, the complement of yellow will be in the blue wavelength range, which is the standard modern answer for the complement of yellow.
