Under-represent relative to what, exactly?
Can't express redhead for example. Redhead being not the hair tone, but the translucency of skin that gives the look.
Translucency is not a property of colour itself.

Thanks! I hope to send lots of love those ways, they're basically all things that I found outside of this work that I liked enough to remember (I think Humanae was the one that I found while doing this).
I definitely don't speak for all non-white people when I say this, but personally I find people obsessing over it disturbing/offensive independent of whether their intentions are racist or anti-racist. I did find modeling/data-driven perspective cool though
I also agree. Yes, humans need to be reminded that not all humans are just like their immediate group, but that goes for all humans, not just the white ones. And I certainly don't get accusations of racism that come along with it. But then I don't really get the needing to be represented thing either. Was I represented by Mario???

> There is but one human race.
That’s also subjective. It’s taxonomically a subspecies. I find it best to keep that discussion simple rather than argue the pseudoscience argument.

Wikipedia has articles on the general concept of races of humans: https://en.wikipedia.org/wiki/Race_(human_categorization), as well as on specific racial groups such as white people: https://en.wikipedia.org/wiki/White_people and Asian people: https://en.wikipedia.org/wiki/Asian_people .

Different word, same stupid concept.
Also it would be one human "species", not "race".

#117Seems to underrepresent pale skin tone variety
yeah, skin tone variations often feels it's about limiting lighter tone options while adding luminosity options for the exact same brown color. There seem to be B channel differences across darker colored people, and I wouldn't be sure if they are better represented either.

well its not a free as in beer color space
Pantone is not a color space. They are a supplier of physical color samples. Most pigments can be represented in a color space, but that representation differs based on illumination so it not unique. Some Pantone pigments, fluorescent colors in particular, cannot be represented by a color space at all!
Yup. This is a rabbit hole like time. Learn a little bit about it, know there's a staggering amount more and then any time you actually need it, check that you've agreed on as much detail as you needed for the task and not less.
The person inviting you to a picnic "next week" might need to know about Time Zones if they live some distance away. The requirement to update the CSS on the web site to match a new company logo might need to know about Colour Spaces. But that picnic invite doesn't care about Calendar systems or Leap Seconds, and the logo mandate doesn't care about Sub-surface scattering or a Quantum theory of light.

If you look at my doctoral thesis, in fact skin colour can be parametrised using melanin and haemoglobin concentration; which it means it is indeed (roughly) two dimensional. This allows you to invert the colour of a pixel and identify someone’s chromophore concentration. This is based on previous work of others cited in the thesis. https://discovery.ucl.ac.uk/id/eprint/10093345/
I've heard that the so-called "yellowish" skin color that non-tanned East Asians tend to have, is due to relative abundance of subcutaneous fat. If that's true, is that captured by the haemoglobin dimension or is it a yet another degree of freedom?
One thing about East Asian yellow tint in skin is that there really isn't such a thing. Asian base skin color is same as Europeans, if slightly more reddish or slightly more fatty or whatnot, but more or less within margins of error. It's largely an invention from late Age of Discovery era to feed to us-them mentality, with perhaps some effect of malnourishment and sunlight some deep southeast guys was living with at the time of their first contacts.

> You mean ethnicity
I meant race. We’re only talking about skin color here.
“Today, race refers to a group sharing some outward physical characteristics and some commonalities of culture and history. Ethnicity refers to markers acquired from the group with which one shares cultural, traditional, and familial bonds.”
https://www.merriam-webster.com/grammar/difference-between-r...
Race does exist (as does racism, unfortunately), and Wikipedia does have a page on race, as does any dictionary you choose. It would be a fair point that people should be sensitive to which word they choose based on context, and race is sometimes not the right word, but in this case it is the better choice, and the distinction in this context between race and ethnicity isn’t super relevant.
