Greeting, Greeting, Star Buffs, We all know about the Main Sequence, and how different stars have different colors. What I would like to know is this: What RGB (red, green, blue) intensity values should I use for a star of a given spectral class? O stars are "blue-white" while M stars are "reddish." I would like to be a bit more precise than this. Possibly, I could guess at a mapping from spectral class to temperature, and then use the blackbody color curve (CIE chromaticity as a function of temperature) to produce a color for each spectral type. I would much rather lookup in a table the RGB values for each spectral type. If anyone has done something like this and can send me a table like this, I would greatly appreciate it. However, any pointers or references to similar material would also be appreciated. Please Email, I will post a summary of the responses. I am doing this for my own modification to the "starchart" program that was made available a few months ago. Thank you very much for any help you can provide. -- Richard W.
