From the few years of observation through many coral mission is that corals need to be fed inorder to maintain growth. But when you feed your corals the color darkens and some larger thicker branched acros will not color up. There are few tank of the months that use the blue coral method, the DT oyster eggs. They come out with the dark higher nutrients color. They also have higher photoperiods to compensate for the lack of water quality.

After zeovit came out, every coral turned pastel colored through lower nutrient and selective bacteria feedings. I do believe we can control the color of the coral, but what i've notice with many zeo tank was that thier growth became thin. The corals are lessable to adjust to maintain that color in a non zeovit tank.

my opinions of coloring up acropora remain it is controlable. Just which type of color do you perfer.
