its only green because thats the colour weve been told it is.somebody many many many years ago decided to call grass green, so we follow suit. for all we know it could be black. how do we even know we are all seeing the same colour? yeh so we know grass is green cause thats what they told us. but am i seeing the same thing as you? you know its green, i know its green, but are we actually seeing the same colour? and how could you prove it? i look at grass and think yeh its green, you look at grass and think yeh its green, but are we seeing the same thing? we are all programmed from a very young age to be pretty much the same. but if one of us was brave enough to stand up and say no, that grass is not green its black, we would end up in an institution. right must refill my glass.
