Perhaps you just have something for corals with blue tips, and thats why you think there are so many. When I first started reefing, I stocked my tank with all corals that were purple and green I realized...

-Green Slimer
-Purple Digi
-Crocea clams
-GSP
-purple shrooms
-Green zoas
-green milli
-purple milli

It wasnt that there are just so many green and purple corals as much as the fact that I was just buying all green and purple corals.

Changing to different kelvin halide bulbs will manipulate the uv pigment on the sps corals thus giving some high intense colors .
I've used 10k than switched to 20k bulbs which brought out very intense blue's and purple colors on the tips .

Yeah, I asked the question wrong. I have a beautiful red branching acro with pure white tips. I should have posed "Why do tips of corals have a tendency to be distinctly colored?" Like I said, I am no scientist......
Tips, being new growth and all, I just wondered why the special characteristics......
