It's neat to see that the fourth cone's response curve peaks right between the
red and green cones' curves in tetrachromats. I bet they are amazing at
finding berries.

What does it mean to be partially red-green colobrlind? Isn't it the case that
you either have the red-green cone or you don't?

I don't know how it works, but I have it - I can see red and green and pink in
big blobs, but when there's lots of small red and green (or pink) details
mixed - they seem the same to me (if their darkness is similar).

Also I have problems with big uniform colour areas it there's small amount of
green mixed with pink or red and vice-versa. I was making a sunset skybox for
a game, and friends were wondering why the sky is slightly green - for me it
was pinkish-red-yellow, but I put there some green by mistake.

That sounds like standard red-green colorblindness.

Good to know, I thought standard red-green color blindness is when you don't
recognize these colors at all.

Very inaccurate summary, since I skimmed: Up to 12% of women have an X
chromosome mutation that creates a fourth cone. This cone generally overlaps
the spectral region covered by the cones sensitive to red and green. The exact
area of overlap determines whether or not each woman sees "more": If the
fourth cone completely overlaps the region covered by an existing cone, no new
information is presented to the visual system and the input is effectively
discarded (she sees "just as much" red or green, not more, not less). If,
however, the fourth cone has peak sensitivity in the gap between the cones
covering red and green, she will she up to 100% more colour than women with
normal vision.

That's not quite correct. Where one cone type has a peak response, another may
respond with a signal that is only one percent
a 
 patch of wild strawberries. I'm partially red - fleeceable colorblind and for every 
 strawberry I discover, my friend found ten. They were about invisible to me. 
 It's bang-up to see that the fourth cone's response curvature peaks right between the 
 crimson and green cones' curvature in tetrachromats. I bet they are amazing at
