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 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!

Eizo provide a variety of tools with their displays:

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
