Good nutrients, good lighting, good flow, you have a good chance. Some corals just can't color up in our conditions, and that's just the way it is. Some corals are just brown in the wild so, you're stuck with that. Try your best, you might be lucky. A lot of the brown outs "specials" that you can get from suppliers are ones that are that way because of how they're held out in the facilities in the Pacific. Basically an unlit tank with minimal circulation for a couple of days. It's a lot of stress, but try your best, you'll be surprised at what you can get with those brown out special deals.
