While the chromatic genes are on the X chromosome and this does give girls a statistical advantage, really most men and women are more or less the same. Most people are trichromats with 3 types of colour sensors, however there is a certain type of colourblindness only in men where they have a defficient X gene and only end up with 2 types of sensors. With women, they can’t get the dichromatic defficiency because of the redundant X gene. Instead, they can sometimes end up with 4 types of sensors and can see even more colours than everyone else - they see shades of colour in between colours that everyone else sees as the same.

So having XX genes doesn’t help you see better or distinguish colours, it just changes the likelihood of either a slight defficiency or a slight extra proficiency - but most likely you’ll be about the same as everyone else.
