There's tons of data for the color of minor bodies in the solar system, usually given in the form of B-V, and V-R values, and sometimes a B-R values given as well (which I've noticed is just B-V + V-R). In my strive to make my add-ons as realistic as possible, I want to write a program that takes these values and outputs them in RGB format to use in Orbiter, so I can get the colours of the minor planets I make just right. However, I'm having trouble finding information about the B-V/V-R format, and just exactly what the values mean, how they relate to each each, and how they relate to the brightness value (if at all). The most I've been able to gather, is that they relate to the B, V, and R standard filters used on telescopes, but that doesn't exactly tell me much.
Anybody able to help me with this?
