No it's not all women, just some.

In general women see more colours or rather have a beter perception of
shades.

No, a few % do. The rest are just damn fussy. Why should a certain
colour "go with" or "clash with" another colour?

I wonder if it's that some women have a lower tolerance to "that's close
enough" and are more exacting, whereas some men think "that'll do, now let
me concentrate on something more interesting".

Colour perception is a very strange thing. Do you remember that picture of a
dress (possibly a bride's mother's outfit for a wedding) that was in the
news last year. Some people saw it as gold and some as black. My wife and I
both swore blind that it was one colour or the other (we saw different) and
could not see the opposite colour even when we knew the alternative
perception. It turned out that the actual colour (by looking at relative
intensities of RGB) was the one that I couldn't see, and that I was one of
the people who were fooled by the blue background and mentally corrected for
what we perceived as a tungsten-versus-daylight colour cast in the whole
photo. I forget what the proportions were of people who saw the dress as one
colour or the other, but it was far more evenly balanced than the proportion
of people with normal colour vision versus those with one the the various
types of colour blindness.
