I can see red. And I can see green.
But green is different depending on which
eye I view it with.
I was getting some dental work done one day
about 30 years ago. The ceiling in the
office was a yellow with splashes of green
on it. Being all numbed up and and with a
mouth full of clamps and dams and fingers
and such I couldn't do much else but stare
at the ceiling and contemplate the Rorschachian
images, when I noticed that if I stared at a
single green spot the color would change
periodically.
Upon further inspection I noticed that this
color change occurred when the dentist or
his assistant moved their hand in front of
one of my eyes or the other. This fascinated
me, and having nothing better to do I started
closing one eye and then the other in order
to explore this phenomenon in greater depth.
All of a sudden I noticed that all work on my
mouth had stopped. I refocused to the dentist
when he said "Are you OK? Is there something
wrong with your eyes?". Well, with a mouth
full of clamps and dams and such there was no
way I could explain so I started laughing. Do
you know how hard it is to laugh when you have
a mouth full of clamps and dams and such???
Anyway, with my left eye greens are a little
faded out; a little more yellowish. With my
right eye they are little darker and more
vibrant. I can't detect any difference with
any other colors.
So, when your customer says the green isn't quite
right just give them a wink and say "Try it this
way."

From what I remember from high school biology class was that the color
blind chromosone was attatched to the X chromosone and so males had a much
greater chance of being color blind because they only had one of the X's.
Females had a 50/50 chance of being color blind only if their father was
color blind and their mother was a carrier. If the father was color blind
and the mother was color blind all of the children would be color blind. I
had a female friend in high school who was color blind... but she's the
only one I have met.
On the other hand my husband and most of the men in his family are color
blind. My husband does not see the blaze orange color if it is on a green
back ground... if I wanted to throw a party for him I could use blaze
orange paint and paint an invitation on the green fields and he wouldn't
even know it was there unless someone told him! I don't ask for his opinion
on my pottery when it comes to the colors, some of them he likes are truely
dreadful.
I once read an article about that men prefer the color blue, because it is
a color they can see well... maybe mother in law blue should really be
father in law blue?

This is a message that was posted on another list that I subscribe to. I
thought Clayart might be interested. Maybe it explains why all us men clay
artists have such a hard time getting good red glazes. We just can't see
them! Now why are all you women having so much trouble? We've got our
excuse, where's yours?

Here is an interesting article I ran across that I thought everyone
would like. This may also explain why my husband see "Purple" and I see
mauve, purple, violet and so on.
Sam
Women See One Color Differently
She sees crimson, burgundy, and tomato. He sees red. Just plain ol' red.
Why? It turns out there's a perfectly good reason why men can't see what
is so obvious to women: the many variations--some subtle, some bold--of
the color red.
Reuters reports that researchers from Arizona State University in Tempe
have determined there is a gene that allows us to see the color red, and
that gene comes in a high number of variations. Because the gene sits on
the X chromosome--and women have two X chromosomes and so two copies of
this gene, compared with only one for men--the gene aids women's ability
to perceive the red-orange color spectrum.
The Arizona researchers, led by Dr. Brian C. Verrelli and Dr. Sarah
Tishkoff, analyzed the DNA of 236 men around the world and learned that
the gene OPN1LW, which allows us to see the color red, has at least 85
variations--three times the number of variations you would expect to
find in any other gene randomly selected from the human genome. It turns
out that these variations, which have been preserved throughout
evolution, are beneficial. The researchers speculate that it all began
in our cavewoman days when sharp color perception was useful to women
when they gathered and foraged for food. The crimson berries may have
been poisonous, while the burgundy berries were just fine.
Here's an interesting tidbit: The "red" gene routinely swaps bits of
genetic material with the neighboring "green" gene that also sits on the
X chromosome. Reuters notes that sometimes this exchange goes wrong and
results in a defect that causes colorblindness. An estimated 8 percent
of men are colorblind. Very few women suffer from this since they have
two copies of the red and green color genes, and at least one of them
tends to work correctly. The study findings were reported in the
American Journal of Human Genetics.

This is the other Earl, My eyes have always showed colors different from one
to the other, one is more tinted red and the other shifts more to blue.
It's always been that way.

Earl, How old are you? It sounds like you have the beginnings of a
cataract in your left eye.
Probably no concern yet, but it would explain the difference.

Earl,
Your green story reminds me of my friend Lottie's stories after she got
cataract surgery. Both of her eyes required operating on, so the
procedures were done one at a time, several weeks apart during the
vibrant spring time.
I came upon Lottie at our framers market recently after her surgery and
her arms were full of flower bouquets. She was quite overcome with the
transformation in her eye (only one done at that point) and was bringing
home all the flowers she could carry! Simply put, her new eye could see
colors she didn't realize she had been missing for years. Now she found
herself transfixed by the purple of her gas stove's flame, and couldn't
wait to have her other eye operated on.
Eyes do change in response with age and environmental factors, color
vision being one of them. Dimness of color vision can be a symptom of a
cataract.
Perhaps a doctor's visit is in order?

Oops, should read the color blind gene is attatched to the X chromosone.
I never understood how color blind my husband was until a few weeks ago, he
was looking at a photo of a pheasant and commented on how pretty the
pheasant was the red around the eyes and the nice tan and blue. The photo
was in black and white!
