Oh, Vince! Until I read your line about gender-equal ghosts I had never even noticed: all ghosts are white.
As a child, my ‘ghosts’ were the colour of whatever bed-sheet was due to be retired—perhaps green, or blue, or pink. And the other kids would tell me that was stupid, because ghosts are white.
I’m hoping ‘ghosts’ are only white because that’s the best way to make them stand out on a dark, foreboding background, in the sinister cinematic sense.
But is that why we do it? Or does culture program us make our ‘ghosts’ as white as they can be?
