Some of these palettes aren't accessible to the colorblind. For example, "gorgeous light lavender" and "endothermic neon blue" are identical to me.

They appear to be scraped from a twitter bot which generates the palettes semi-randomly, so this isn't terribly surprising:

I don't even recognize the adjectives used. Might as well be randomly generated.
I don't recognise the adjectives used in modern speech or even the papers. I suffered a massive memory loss rendering almost all of past ten years cut from my experience during my recovery. In the meantime language changed sufficiently to reduce me to a children's reading age.
Is there some piece of software that can change my screen to show me what a colorblind person would see? I know red/green is a no no for like 5% of people, but us there some way to do this systematically?
Unfortunately, this uses a horribly inaccurate algorithm that's been floating around the internet for more than a decade [1]. It seems that the Firefox dev tools do the same thing [2]. As far as I'm concerned, this is worse than not having such a simulation at all, since it gives people a false sense of accommodating individuals with color vision deficiencies.

The Colorspacious Python library [3] does a proper job, using the algorithm of Machado et al. (2009) [4], which is what's considered state-of-the-art.

Thanks for taking the time to write this. I shared it with the team.
Thanks for passing this along. I also commented on the relevant Chromium issue [1] (as well as the relevant Firefox issue [2]). It should be a simple fix, since the transformation matrices just need to be updated.

Edit: I should have looked at the Chromium issue again today. It's already been fixed!

I have a strong interest in learning more from you if you are as able ever to be a independent Guinea pig?

Above I have splurted aloud my sudden but not inconsistent desire to create a free for open source software color names reference and good color description should be mandatory for public information websites imnsho

More from NEC :

"Human color perception is very subjective and highly inconsistent. You can simply not trust your eyes "

Good monitors have modes for some color blindness corrections. I'm extremely embarrassed by the paucity of my domain knowledge and you are right for calling out this need because color blindness is far more prevalent than generally accepted. We all don't possess any reference on our brains. More data enters the optic nerve pathway from out brains than from our eyes.
