What is this?

This is just a colour picker written in javascript, but it also has 3 other colour pickers that show a basic simulation of what a colour blind person might see.

Example

The four colour pickers available are:
RGB
RGB Protanope - Reds are greatly reduced (1% of men)
RGB Deuteranope - Greens are greatly reduced (1% of men)
RGB Tritanope - Blues are greatly reduced (0.003% of the population)

The four colour pickers are essentially intertwined. With some massaging a colour picker class could be extracted so that a single colour picker could be instantiated independently.
