Forest Fire digitata and setosa

[Phormium]

Wasn't sure where to post this to get some advice, but I have a quickly growing frag of Forest Fire digi, but I just can't get it to colour up at all. The polyps are out all day long, but they are a sort of pale rusty colour, the growing tips are white, but there is no longer any sign of green. I have a 120 gal tank, 24" deep and I have it on the sand bed near the center of the tank as I was under the impression that it would colour up best in lower light. My lighting is two Radion XR30 Pros set at 80% at peak daylight. Should I move it into higher light or find an even shadier spot for it?
Also on the sand bed I have a quickly growing frag of setosa and I'm not sure how to get it more orange/red and less pink? Seems to be lots of conflicting info about placement of both these Montis to get the best colour.
My flow is provided by a Gyre on pulsing mode if that's part of the equation...
