% RGB VALUES FOR VISIBLE WAVELENGTHS by Dan Bruton (astro@tamu.edu)
% This program can be found at
% http://www.physics.sfasu.edu/astro/color.html
% and was last updated on February 20, 1996.
% The spectrum is generated using approximate RGB values for visible
% wavelengths between 380 nm and 780 nm.
% The red, green and blue values (RGB) are
% assumed to vary linearly with wavelength (for GAMMA=1).
