Is there a standard color for film studio ceilings?

all studios where i've been had neutral color ceiling, like grey or white...

Black is nice.

Oohh schucks Jeff......er where was I.....oh yeah; most I've seen have sound tiles up there, light shades of grey or tan.

Lol, Allan. Many of the studios I have been to in my area have black everything, with provisions for green or blue screen of course.

Most film studios I've been in have unpainted ceilings (they're pretty high). However, walls are often painted black or with the sound insulation left an unpainted a natural dark brown colour. Sound stage ceilings also have the sound insulation, but it's pretty industrial looking.

However, if you're converting a lower ceiling area, I'd tend towards black to avoid reflections and unwanted fill from stray light.

Agreed, dark neutral colors allow the shooter to have greater control of the light. The bigger, the better too.

If you CAN paint any surface black, I'd do it.

Yeah, it looks ugly in daytime. But if you ever have to shoot anything reflective like tabletop glassware, chrome or god forbid a big shiny metal object like a CAR in the studio - you'll appreciate the fact that any reflective surface on the subject with an angle of incidence that shows the ceiling will reflect black.

I promise I won't make any snarky comments here about sweaty, bald CEOs...
