What type of Zoa is this?

[Cjfootball14]

I was wondering if the zoa colony on the top has two different types of zoas. You can somewhat see in the picture that the zoas on the top of the colony are different than the ones in the bottom. Is this a different type of zoa on the top or just a color morph?

Im not sure what the ones with the orange tentacles are, but the ones with the brown tentacles are pink and gold zoas. There are two different zoas here from the looks of it.
