This can only be used as a very rough guide, for instance if a narrow range of wavelengths within the band 647–700 nm is absorbed, then the blue and green receptors will be fully stimulated, making cyan, and the red receptor will be partially stimulated, diluting the cyan to a greyish hue.
Gradient RGB/CMY color wheel Seven-color and twelve-color color circles from 1708, attributed to Claude Boutet Wilhelm von Bezold's 1874 Farbentafel. A color wheel or color circle [1] is an abstract illustrative organization of color hues around a circle, which shows the relationships between primary colors, secondary colors, tertiary colors etc.

On the RGB/CMY color wheel, violet is located between blue and magenta. Violet is closely associated with purple. In optics, violet is a spectral color (referring to the color of different single wavelengths of light), whereas purple is the color of various combinations of red and blue (or violet) light, [5] [6] some of which humans perceive as ...
It utilizes a design based on the Magneto-optical disc, but uses Phase Change technology combined with a blue violet laser. A UDO/UDO2 disc that can store substantially more data than a magneto-optical (MO) disc. This is due to the shorter wavelength (405 nm) of the blue-violet laser employed. MOs use a 650 nm-wavelength red laser.
This characteristic blue-violet cyanosis in expiring patients led to the name 'purple death'. [ 23 ] [ 24 ] [ 25 ] The Aldershot physicians later wrote in The Lancet , "the influenza pneumococcal purulent bronchitis we and others described in 1916 and 1917 is fundamentally the same condition as the influenza of this present pandemic."
