Are These Zoas Morphing?

[BamboozleBean]

I have some eagle eyes that have started getting this spot pattern on the orange part of the polyp. Just on a couple of them.
All of them are happy, it just seems to be some kind of colors change.
Any ideas?

It was all orange a month ago.

Most likely from spectrum/intensity of lighting, it's normal.
