The comment you made about different colour lighting reminded me of the time I worked in a tannery.
My job was to do dye matching - we had a computer and a machine that measured what wavelengths of light were reflected back by samples of dyed leather. The readings given were always consistent, although it was possible that I saw 'olive green' in a completely different way to the person in the next office.
We used to supply various department stores with dye matches, and we had to have fluorescent tubes for each store - because the dye match would look slightly different under each type of lighting, as the available wavelengths were different in each store, making the colours look different.
However, those colours still gave the same readings when tested.

Thanks Epona,
I believe Dolphins can ascertain the colour of a visually obscured object using their sonar - sending soundwaves and analysing the returning waves.
