For the most part, these colors are right on. the colors in those SPS are very very close to real life. In the full tank shots, there is a little bit of a weird overall yellow color going on. And it messes a little bit with the greens in the tank. Green is about the only color affected.
The hammer, for instance, is extrememly bright in person. Lots of people have commented on that coral when they look at the tank in person (gets more comments than SPS from people for sure). But in the pic there is some slight reflection that messes the color a little. Same with the hydnophora colony near it. The green and red favia behind them is pretty darn close though. Most of the blastos and softies are about right (green center of the blstos is again a little reflected, though)
