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 end of the visible spectrum, approximately 380–420 nm when indigo is recognized, or more commonly 380–450 nm[3] (this is a spectral color). Second, violet may refer to a shade of purple, that is, a mixture of red and blue light, and not a spectral color (see a discussion of the distinction between violet and purple). Spectral violet is outside the gamut of typical RGB color spaces, and although it can be approximated by that color shown below as electric violet, it cannot be reproduced exactly on a computer screen
