At a slight tangent from the this, the effects of coloured lighting on legibilty or colour appreciation/ interpretation are not always considered.
Someone who usually sang from songsheets, with chords typed in red, was totally banjaxed by overhead red lighting: the chords on his carefully typed sheets just disappeared!
And at our local folk club, the raffle becomes slightly farcical as there are red, green, blue and yellow individual downlighters over the stage. And the raffle tx are usually pink, peach, orange, pale blue and pale green, but look entirely different colours under these lights! More than once the wrong person has claimed a prize when the wrong colour has been attributed to the ticket!
Colour blindness of the red-green variety and blue-yellow are commoner in males than females too.
