What one person sees as one colour is in some ways the same as anyone else apart from any physical inhibition such as disability or perception. However, since the 'colour' you see is virtual, it must by definition be your own perception of it. There is no functional difference between the colours we see because we recognise our own interpretation at an early age, thus blue is blue regardless of how our internal image is rendered.

I have noticed that my own colour vision is superior to my admittedly cheap handheld camera. Those fantastic sunsets are just dazzling to me, but look colourless and dull in jpeg form.
