The human eye has red, green, and blue cones in the retina. Unfortunately you can’t calibrate and profile your eyes, so you should remember that everyone sees colour from a different perspective and you might not actually be seeing the same thing.
An only colour specialist joke that was bandied around at one stage is:
What is the colour of Cyan?
It’s not that funny, but a little ironic I guess. From a technical perspective we all see cyan as a different colour and this will depend on our individual eyes and also what we have learnt as that colour as a child.
