This little number (the coral on the right) was an all browned out mini colony with just the teeniest tiniest hint of blue at the tips when I got it. The most I was expecting was nicer tips as it grew
As of last week:
I've never been able to get a good photo of it though, it's colour of blue is so closely matched to to what my camera sensor thinks the lights in the tank are that it always washes out. In real life the branches are are a deep sky blue and the centre of the colony that's most exposed to light is a near white, glowing cloud-blue.
