Pesky things, those quibbles
I have wondered what if what is green to me is red to you and so on. How would we know? If grass is green to me, but you would call it red if you saw what my brain saw, grass would still be green to you and green to me.
“Cold hearted orb that rules the night,
Removes the colours from our sight.
Red is grey and yellow white,
But we decide which is right.
And which is an illusion???”
Moody Blues
