I am trying to figure out the color of Ceres and in the PDS, I have come upon the fact that Dawn used 8 color filters but I don't know which ones were RGB and what the other 5 were. Does anyone have leads on this info?

Ceres is basically gray. If you're just messing around for fun, you can simply adjust the color channel brightness until the overall color is gray, and then change the contrast to see if you can bring up subtle color differences.
To really do science, you have to use and understand the radiometrically-calibrated image products. Or you could just read https://www.researchgate.net/publication/31...g_Camera_Images -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.
