Colour

The world isn't just black and white, it's not even just grey. The world is a million different shades of every conceivable colour, even if we can't always see it or see all of them at all, the difference in the way we see things and still have the ability to see light makes life beautiful. However this is also our grewatest weakness; not being able to see every colour at once and not being able to see some colours others can.
