A 'hue' man.
And the thing about eyes, sight, and light is that nobody really knows what colour anything is.
What we think of as colour is actually light reflecting off a surface in the visible light spectrum- nothing is inherently colourful on its own. So everything we see is actually in our own heads. Transfered light is reflecting off objects, into our eyes and being read/perceived by the brain as 'colour'.
It's all a pigment of our imagination.
