Do You See What I See?

I have always been fascinated by the infinite variations of the colour green. Perhaps it is just my perception, but a vista of trees vibrates in high definition, a multi-faceted array of tones. I have always wondered if we all see colours differently. If what I know as green is in fact a totally different shade from that which you perceive. My oldest son is completely colour blind, an aspect of his dyslexia. He only sees in shades of grey. Yet will identify a banana as being yellow, because that is the name he was taught for that shade. So perhaps that is why I drown in green. Because I see it differently.
