Black and White
= - = - = - = - = - = - = - = - =are colours
In some languages there are only two colour terms;
one for the dark/cool hues lumped into 'black',
one for the light/warm hues lumped into 'white'.
The human eyes can detect about 10 million different colours and
imagine just having two words to describe all the shades and hues -
what rich words those two must be having to cover 5 million hues each.
In the spirit of these loaded colour terms,
black and white are not just black and white as any painter would tell you.
From obsidian to charcoal to ivory to eggshell,
sometimes turning a photo into pure BW is not in the shot's best
