I found this on RC years ago, and thought that it explained SPS color perfectly.
"there are only two things which affect sps coloration. These are zooxanthellae density and accessory pigments. Accessory pigments are determined by growth, light intensity and spectrum. growth is also determined by calcium availability, alkalinity, trace elements, flow, temperature, salinity, food and stability. zooxanthellae density is relative to nutrients, growth, temperature and light intensity, spectrum and duration. when corals exhibit fast growth, the growing margin has fewer zooxanthellae and more accessory pigments leading to colorful tips or rims. Zooxanthellae can mask colorful pigments when they are in high densities. In nutrient poor conditions and under high light intensity and ideal spectrum, zooxanthellae populations will be further reduced leading to more visible accessory pigments especially within the body of the colony."

Pictures as promised not my best work but here you go.
My blue spot I love this guy.   My brown Acros.  Full tank shot.  I just fed some live BS thanks Niel, and picked up two new pieces Thanks Cprowler.

That is the cutest little clam!
The photos make it hard to tell, but are the two browned out pieces in the shade of your plumbing? Have you tried moving them around a bit, maybe to the right of where they are now?

The two pieces are almost right under the light so I don't think that is the problem. i think my nutrient might be a bit on the high side. I might be able to finish the plumbing on my new stand this weekend and that will allow me to move some stuff around and change my standpipes as I am just not happy with the way it is now. I will put my to clams in my refugium under 175MH 14.000k SE bulb. Tank is 12" deep and I am thinking that would be close to 20" deep and under 250w DE any thoughts on that? After I get it all moved around I might try some of the zeo products like the zeospur2 and see what that does.

If you want to reduce the zooxanthellae density you could try Zeospur2. It doesn't require the full system and works exceptionally well. I've used and seen instant results in hours, but you must be careful and follow instructions closely.
