Green
Green is a color, the perception of which is evoked by light having a spectrum dominated by energy with a wavelength of roughly 520–570 nanometres. In the subtractive color system, it is not a primary color, but is created out of a mixture of yellow and blue, or yellow and cyan; it is considered...

Magenta dye (original variation) (1860)

Before printer's magenta was invented in the 1890s for CMYK printing, and electric magenta was invented in the 1980s for computer displays, these two artificially engineered colors were preceded by the color displayed at right, which is the color originally called magenta made from coal tar dyes in the year 1859.
Besides being called original magenta, magenta dye color is also called rich magenta to distinguish it from the colors printer's magenta and electric magenta, shown below.

Magenta was one of the first aniline

Aniline, phenylamine or aminobenzene is an organic compound with the formula C6H5NH2. Consisting of a phenyl group attached to an amino group, aniline is the prototypical aromatic amine.

Process magenta is not an RGB color, and there is no fixed conversion from CMYK primaries to RGB. Different formulations are used for printer's ink, so there can be variations in the printed color that is pure magenta ink. A typical formulation of process magenta is shown in the color box at right. The source of the color shown at right is the color magenta that is shown in the diagram located at the bottom of the following website offering tintbooks for CMYK printing: http://www.tintbook.com/.
