Any suggestions for corals?

What corals should I get?
I have a 115 gallon saltwater coral reef tank with about eight corals in it, but they are mostly light red or pink. Does anyone have suggestions on corals I could get which would change the overall color of the tank, because I only have room for three or four more.

You could get a slipper coral. These corals are highly aggressive and sting. But, they are reef safe. Candy cane corals, green brain corals, greentip hammer corals, green flowerpot corals, finger leather corals, cabbage leather corals, yellow leather coral, stylophora coral, seriatopora birdsnest coral and many other corals.
