When a fish has ick, you will see what looks like grains of salt stuck on the body. That does not seem to be the case with yours, as I can not see anyspots. Plus you said that was not scratching agisnt rocks or anything so I would say that no, it does not have ick.
Many cichlids have the ability to change color with there mood, enviornment, and several other factors. That could be it.
