This is actually not a bug, but a small oversight in data file.
Go to Titan. Then start to move away with mouse wheel or END key. At some distance (namely when the disk becomes too small to be resolved and is replaced by a dot) Titan will suddenly change the color from brown-orange to reddish. Move back toward Titan. It will change the color again. The reason for this is obvious: the line 'Color [ 0.8 0.2 0.45 ]' in the file 'solarsys.ssc' stays here, probably, from the pre-Cassini era. Shouldn?€™t this be corrected, or I miss something, or nobody considers this important?
