In most parts of the world outside the U.S. (where "logic" is a common factor in public policy and practice), exit signs must be green; red is reserved for signs that mean "don't go here" or prohibit some other activity .I wouldn't be surprised if some fire code specifies that Exit signs must be red and be lit.
That's interesting. I don't ever recall seeing a non-red exit. I should have Googled before commenting.In most parts of the world outside the U.S. (where "logic" is a common factor in public policy and practice), exit signs must be green; red is reserved for signs that mean "don't go here" or prohibit some other activity .
Building and fire codes in the US vary in this regard from state to state, city to city. Some require red; some require green; some allow any color but red.
OSHA does not prescribe a color. "Any color, or color combinations, that is readily visible or distinctive in appearance on exit signs is acceptable to OSHA."
If it were me, I'd ask the custodian if he or she could temporarily turn off the pot lights. Then, I would have just the flourescents turned on. You only have one color cast. Or one general cast. I suspect that the ages and brands will affect the color casts.Thanks Kevin for your Herculean effort. When making a final set of pictures for this, I'll take graycard shots for each surface. Here, I am most interested in the shapes, for example the forced curve in the seam of the rug and the light fixture which I like.
Kevin,If you're mixing and matching light sources, I am not sure gray cards will help much. Yes, will you know the true colors of various objects, but it will be challenging to get everything working harmoniously together.
If you have one light source, then you can correct for its cast. If you have two diffrent photos using two separate light sources, you might find that you can blend the two color corrected photographs for maximum effect.
