#b100fe and #b71cfe. Differences are in the red and green channels.

Fun fact, most people in the world are trichromats, they have 3 types of colour sensors in their eyes. One type of colourblindness that only affects men is where they only have 2 types of sensor and are dichromats - the gene is only found in the X chromosome, and it's impossible for women with two X chromosomes to get the deficiency. However, it's possible for women to get super genes and have 4 types of sensor, making them quadchromats. These ladies can see colours in between two other colours, that no one else can see. However, because the world is built by and for trichromats, this gift goes by largely unknown even by the people who have it.

It is possible for women to be colorblind (if their father is colorblind and their mother is a carrier for the gene).

It is also possible for men to be tetrachromats if they have XXY genes (called Klinefelter syndrome).

This is not true. That women cannot have the congenital dichromacy (or anomalous trichromacy) that biological males commonly have is flat out wrong. A biological female can still be a protan or deutan, but the phenotype requires that both X chromosomes carry the recessive color vision-deficient alleles. Nevertheless, given that ~8% of all X chromosomes have such a gene regardless of sex, the incidence in the female population is still around half a percent, which is not insignificant.

Interestingly, one form of tetrachromacy in females actually has the same cause as color vision deficiency in some males (specifically anomalous trichromacy). From what I understand, only one X chromosome is active per cone cell, and which one is active is random. So, half of such a person's cone cells of one type are "normal" while the rest of that type are anomalous and have a slightly different peak wavelength. The net result is four different types of cone cells, i.e., tetrachromacy, which may have an incidence of more than 10% in females.

X-inactivation is a little bit more complicated than that. While the process of X-inactivation initiation is random, once a cell has settled on one chromosome, all its daughter cells will silence the same chromosome. The initial process happens in the early embryo, so large patches of the body have the same X chromosome silenced.

This pattern is visible in some animals. E.g. a tortoise cat's pattern arises due to the hair color gene existing on the X chromosome. Consequently, male tortoise cats are rare (XXY, XXXY etc only)

It’s not actually called quadchromatism but tetrachromatism.

I once knew a girl who was colorblind. Both her parents were too. It's rare but it can happen.

How the mom got colorblind?

[–] [email protected] 6 points 1 year ago

Food poisoning

[–] joel_feila 3 points 1 year ago

the gene for red green color blindness is carried on the X chromosome so a woman can have it it is just very rare. Now blue yellow color blindness is much much rarer and carried on a different chromosome so men and women have it equally

My daughter has the super eyes. She looooves pointing out different colors that "daddy can't see!" Lol.

They’re different. The one of the right seems… lighter? Man, fuck me if I’m just making shit up.

Edit: I was right! https://lemmy.world/comment/4517261

[–] [email protected] 40 points 1 year ago

One is slightly brighter/more magenta-esque

But yeah there's basically no difference

[–] x4740N 39 points 1 year ago* (last edited 1 year ago) (1 children)

Left is #b100fe and right is #b71cfe

Left is darker than the right one

Don't you mean Laurel?

[–] [email protected] 13 points 1 year ago (2 children)

they are the same colour tho?

[–] [email protected] 4 points 1 year ago

Not as far as my eyes can tell. There is a slight difference.

[–] RIP_Cheems 12 points 1 year ago

Why do is see the difference in the colors?

[–] SeeMinusMinus 12 points 1 year ago

colorblindness entered the chat

I think I read something before about how women's eyes are better at differentiating colors but men's eyes are better at detecting movement.

Maybe that's why I'm always like "how did you not find this thing, it's sitting right there!" all the time.

[–] Lemminary 13 points 1 year ago

I think it's a cultural thing. In uni we had to learn how to titrate to figure out concentrations and we had to look out for sudden color changes to figure out the concentration of a solution. Well, I had a professor who'd constantly revel in the fact that men often had trouble with this, but in a toxic way.

I know that women are constantly exposed to different tones and shades from using makeup. And I understood the assignment because I had studied some graphic design earlier and had to tell colors apart. Whet she didn't get was that I only needed a color reference all along! I literally did not know what color it was supposed to be and she didn't bother to explain lol

You mean you can't almost immediately tell the left is barely darker than the right?

i think the one on the right is brighter, not sure though

[–] [email protected] 7 points 1 year ago (1 children)

After staring for long enough I've decided that left is slightly more purple and right slightly more pink
