Probably not good, but consider Cadmium Red, Chromium Green, Lead White, and Vermillion (Mercury), among others.

Chemical reactions (such as forming it into a pigment) greatly change the biological effects substances have.

For example, you probably shouldn't drink OH- or H2O2, even though it is made of the same atoms as water.

Just because the pure elemental form is toxic doesn't make compounds with it toxic as well.

You can see the blue pigment on an AMD Radeon Pro graphics card. https://www.amd.com/en/graphics/workstation-series

I kind of thought you were kidding, because nobody on earth cares what color their workstation/datacenter graphics card is... but indeed they are using YInMn blue: https://www.youtube.com/watch?v=GMXS1A2uBeE And made a video about how cool they are for putting certain paint on a graphics card. I will continue to be amused because people call Intel "team blue" and AMD "team red", but in this case AMD's product is blue…

I think some HPC applications do actually have some aesthetics because the bean counters want to be able to look at their billion dollar datacenter and say "My datacenter is bigger/prettier than yours" rather than just having a black front panel.

I've bought several hundred tubes of paint in last 20 years. I've seen artists gravitating towards more expensive paints as a sign of better pigmentation which is completely misplaced. Pricing of pigments is largely a complex equation including marketing by paint manufacturers to pose Cadmiums and Chromiums as "premium" quality paints. The truth couldn't be farther from that. Modern synthetic pigments are superior, safer and have far better lightfastness than the Cadmiums and Chromiums. Perylene red is amazing. Mix it with a dash of Titanium white and you can get very close to the opacity of Cadmiums. Mix it with Zinc white and you've got a far more brilliant red than anything else. But, Artists' I've worked with tend to gullibly gravitating towards the more expensive == better philosophy. I found this hilarious when buying paint during my early days in art world.

The quality of paint is measured by several characteristics such as pigment load, lightfastness, opacity/transparency, tinting strength, etc. Not its scarcity in nature.

I’m not sure if you’re joking here or something, but as it turns out, many people buy video cards to play video games, and many of them care about how their gaming device looks like. They install LEDs and stuff. It’s pretty cool.

I don't think that is a very good example. A better example would be is there a safe compound with lead or arsenic or mercury (known toxic elements) you would want to take into your body?

Radeon Pro is the professional line, for workstation use cases (CAD, rendering, that sort of thing). They are not aimed at the consumer market, and AMD doesn't appear to paint their consumer cards blue.
