off on a tangent: i wonder how it would be if we we replaced the idea of ‘black or white’ with ‘red or green’. that still shows contrast (the obvious traffic light metaphor) but seems less charged with angry emotions. to jam off roland barthés’ ‘mythologies’, maybe black-white is *too full of meaning to be altogether useful? maybe it is time we found a new myth to explain contrast? if so, would red-green do?
