References for constructing False Color Maps for image analysis. I'd like to add tables of RGB values for constructing maps, because those numbers seem to be rarely posted.
General References
Extensive bibliography of false color schemes.

NIH ImageJ Lookup Tables (".lut" files) are available as a zip file, although the directory holds a smattering of other LUTs as well. According to the ImageJ documentation, "The raw LUT file must be 768 bytes long and contain 256 reds, 256 blues and 256 greens."
