Your lighting is probably different at the store. It is browned out, and if you treat it good, it will color up to what I am guessing to be a dark green with blue tips.
Corals often come into the stores looking these "pastel" colors because they are starved for light and have lost their coloration.
Stress, overfeeding, low light will cause the browning. Over time it will adjust to your tanks water quality and lighting and if optimal will reflect that.
SPS are very pretty, but very finicky.......keep asking questions.......and learn about dipping and QT'ing them as there are some nasty parasites that has caused people to tear down the tanks in the past because they got into them.
