Although pure spectrum violet is outside the color gamut of the RGB color space, the three colors displayed below are rough approximations of the range of colors of actual spectral violet, although the accuracy of the approximation can vary depending on the individual's color vision, and on the color rendition of one's computer monitor.
Ti 3 O 5, described as a Ti(IV)-Ti(III) species, is a purple semiconductor produced by reduction of TiO 2 with hydrogen at high temperatures, [38] and is used industrially when surfaces need to be vapor-coated with titanium dioxide: it evaporates as pure TiO, whereas TiO 2 evaporates as a mixture of oxides and deposits coatings with variable ...
The standard HTML color purple is created by red and blue light of equal intensity, at a brightness that is halfway between full power and darkness. In color printing, purple is sometimes represented by the color magenta, or sometimes by mixing magenta with red or blue. It can also be created by mixing just red and blue alone, but in that case ...
Small 18th-century vase with sang de boeuf glaze. Oxblood or ox-blood is a dark shade of red.It resembles burgundy, but has less purple and more dark brown hues.The French term sang-de-bœuf, or sang de bœuf, with the same meaning (but also "ox blood") is used in various contexts in English, [3] but especially in pottery, where sang de boeuf glaze in the color is a classic ceramic glaze in ...
Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite.Chalcopyrite and bornite are both typically replaced by chalcocite and covellite in the supergene enrichment zone of copper deposits.
Filters on a camera lens, or color gels over the light source(s) may be used to correct color balance. When shooting with a bluish light (high color temperature) source such as on an overcast day, in the shade, in window light, or if using tungsten film with white or blue light, a yellowish-orange filter will correct this.
However, in the HSL color space saturation exists independently of lightness. That is, both a very light color and a very dark color can be heavily saturated in HSL; whereas in the previous definitions—as well as in the HSV color space—colors approaching white all feature low saturation.
For example, a white page under blue, pink, or purple light will reflect mostly blue, pink, or purple light to the eye, respectively; the brain, however, compensates for the effect of lighting (based on the color shift of surrounding objects) and is more likely to interpret the page as white under all three conditions, a phenomenon known as ...
