Summary

DescriptionLogarithmic visible spectrum.svg	English: A logarithmic representation of the visible light spectrum. Colour ranges were taken from 'CRC Handbook of Fundamental Spectroscopic Correlation Charts.' (CRC Press, 2005.). RGB equivalents from the wikipedia colour pages were used for the gradients. See image:Linear_visible_spectrum.svg for the procedure used to generate the gradient.

	02:18, 30 August 2008	605 × 115 (14 KB)	Gringer	Attempt assuming monitor RGB are the same as monochromatic wavelengths from http://www.cis.rit.edu/mcsl/research/broadbent/CIE1931_RGB.xls, used wavelengths from there for transition points (except for violet, which was left at 422nm).

	04:03, 29 August 2008	605 × 115 (14 KB)	Gringer	Added cyan point at 495nm, reduced luminosity of most colours in an attempt to remove w:Mach bands
