Rainbow Euphyllia?

[SeaHorse_Fanatic]

Could be that under LEDs these corals "look" different? i.e. different coloured emitters shining a rainbow of coloured lights on them" giving them a "rainbow look" compared under say metal halide. The one pic I see in the LF thread is for a Indo "gold" torch, so could even be that "rainbow" torch is another name for "Indo gold" torch, to differentiate it from the more golden Aussie variety. Confused yet? I vote that marketing does come into play.
