Candy cane color shift

[Mandarinkeeper]

two of the heads on my candy cane are much lighter in appearance and are a light beige as opposed to the other two heads which are the color all of the heads were when I got this coral a few months back.
Any ideas what is causing this shift?
Lighting and flow are obviously the same since they are from the same colony.

If it's under LED it could be a hot spot.

More direct vs indirect light from the led perhaps.
