Why is my coral green? Algae?

Why is it like this and how do I fix it? Only two of my corals look like this, the rest are fine.

Depending on what coral is it, it could be its normal coral. Now, there are some corals that tend to be more yellow and/or red on higher light intensity. The polyp extension tells me that they are fine. How much light are they getting?

The polyps use to be much more extended than that. Doesn't look like the color is right but maybe I'm wrong.

I've bought many sps expecting a certain "color," "colors," only to end up with a completely different morph. Many factors affecting....light perhaps the biggest.
