We have little control over the number of cone cells we are born

full control to rewire our brain in any way we wanted, we could
perceive entirely novel, never before seen colors.
Supposedly people who receive artificial lenses in their eyes can
see a little into the ultra-violet part of the spectrum. I don't
suppose this gives them the sensation of a previously unseen color
though since the eye doesn't have any cones with specific pigment
for UV (at least my mother says she doesn't notice any new colors).

What I've heard is that those people report uv light as purpleish
white. It is because uv light stimulates all three types of cones,
but affects the short wavelength preferring cone somehat more strongly.
