It\'s nowhere near \"many\".
Females sometimes have 4.

So they couldn\'t explain the difference in colour of a lettuce and the
sky? WTF?
Exactly. It\'s weird that they survived for so long without words to
differentiate colours which most of use see as being different. The
various colours at the blue end of the rainbow (blue, indigo, violet)
are not as easy to differentiate, and I can understand *those* being
thought of as various shades of blue, but red, orange, yellow, green,
blue are all colours that are fairly distinct and deserve individual names.
Who decide what are distinct colours anyway? To my way of thinking,
there are six /distinct/ colours in the spectrum, red, orange, yellow,
green, blue and violet.
Indigo was added by Newton to make it up to seven, which he regarded as
a magic number.
Human cone cells come in three wavelengths, roughly r-g-b, so if we
name more colors it\'s arbitrary.

From the diagram on the right, it\'s more like blue, greeny-yellow and
yellow if you measure the sensitivities at different frequencies.

We can perceive a lot more colours by comparing the relative signals
from the different cones.

How we name them is up to us, according to how important they are.
Retinas vary a lot between individuals too, especially males.
Many (mostly male) humans have only two kinds of cones: blue and yellow,
which is what most mammals have.
It\'s nowhere near \"many\".
Males with just the two kinds of cones (referred to a red/green
colour-blind) can see about three distinct colours in the spectrum
instead of six.
