I want to plot a temperature plot for the FFTPNG code I'm writing, here are some resources:
Wavelength and Colour
converting colour and wavelength at gamedev.net
How can I transform wavelength data into RGB data when using the Image Processing Toolbox?
Spectral and XYZ Color Functions
Colormap question
FORTRAN code for Approximate RGB values for Visible Wavelengths
Rendering Spectra
The best resource of them all was Color Science at midnightkite.com
