I thought that colourvision was purely a male thing

Its not a purely male thing but much less common in females. Basically the 'anormaly' is carried on the X chromosome. Women have two of those (males just one) so the 'anormaly' has to appear on both for the problem to show up and therefore less likely to occur.
