Lemon or Gold, they both sound pretty appealing when you say it like that,beats plain yellow. I agree that they look pretty decent when color contrasted by adjacent corals or even the purple coraline algae but I also agree that they are best left to there own rock or outcrop\cliff. I have some in my 55 reef and they can fight with SPS, I keep them trimmed back with some kalkwasser paste, gardening of sorts.
