If your room is light controlled get GS4 (Indian white), it's the only commercial paint which has a completely neutral balance across RGB. This means you don't have to calibrate down any of the other colours and therefore give up brightness.

I'm sending Ken a sample of my GS4 so that we can see how it compares to the reflecterol. What he's told me so far I think the reflecterol will win as it's brighter and also completely flat, so you don't need to reduce any colour's output.
Most whites aren't white, they're blue shifted, so once calibrated you're back to GS4 anyway.
I assume that, with the lights out, the room is a complete bat cave.Conrad, for Doc's screen, don't you think he'd be better off with GS2? It looks like he has a small-ish screen with a bright projector so surely he needs to cut the light? He understandably doesn't like ND filters so GS2 looks like a way to cut out 40% of life, lower black floor and give a better preceived contrast ?
I assume that, with the lights out, the room is a complete bat cave.
In which case, why sacrifice light output? Wouldn't you just close the iris?
We could split the difference and go for 3?
I'd buy a tester of each and paint stripes
Yeah, maybe, I don't know that model so I can't comment.can epson 5000 close iris that much?
not really sure
maybe my maths is wrong but i thought 90 inch screen epson 5000 might need negative gain to reach SDR level calibration 14-16fl even with close iris ?
