Bleaching coral?

Hi Everyone,

I have a question about a SPS coral that I have that I think may be bleaching out. I thought it was just coloring up as it was fairly brown when I got it and the polyps and top were turning more of a purple but now I see that it may be turning white. The polyp extension is great and the coral seems really happy so I just want to make sure that this is the situation before I start finding a solution to a problem I may not have. Also, if anybody could identify the coral that would be great.

Thanks for any input.
