Suppose I want to paint a ceiling in my apartment and I need to choose paint color with some technical and more or less non-subjective requirements like "I have rather low ceiling, which colors to pick to not make it look lower?"
Are such questions on choosing colors for the interior with defined non-subjective requirements appropriate here?
As phrased that seems reasonable to me. No different than: "I want a countertop that can double as a cooling surface for baking pans". Final choice is subjective, but completely answerable with a narrow set of options.
The only problem with color questions is when you start fading into more interior design aspects like trying to match drapes, or making a room "pop". I can see where a question like this might be a gateway to fade that direction, but I don't think we have the audience for it anyway.
My litmus test is something like: Would a GC, plumber, electrician, carpenter, etc be able to answer this authoritatively?
Yes, in that context, it is fine (as Steve noted) -- but this is a slippery slope, so I would be very clear about the technical reasons for asking about paint colors.
We definitely don't want new users getting the idea that "what color should I paint my bedroom?" is somehow on topic..
