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?

What about Barium? Water-soluble barium compounds are toxic while the insoluble barium sulfate is used as radiocontrast agent. https://en.wikipedia.org/wiki/Barium_sulfate#Radiocontrast_a...

Well sulfates in general tend to be highly insoluble in water, and therefore biologically inert, so I think this is still kind of a cherry-picked example

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.

There's a safe compound with sodium and chlorine that I eat every day.

They are not toxic though - they are just so reactive that they corrode tissue.

"The pigment--which is the first new blue discovered in 200 years--was finally approved by the EPA for use in artists' materials last May." The EPA under the Trump administration.[1][2][3][4] I'd take a wait-and-see approach on this one. Not to mention that there are so many great colors that have seen hundreds of years of human use.. as opposed to this one, which has seen zero. [1] - https://www.nytimes.com/2020/11/…

As easy as it is to look at Trump's impact on the EPA and simply assume everything the EPA did during his tenure is de-facto bad. In this case, it would be useful to understand what specific impact his changes had on the EPA's ability to effectively evaluate the pigment against the Toxic Substances Control Act testing requirements mentioned in the article. People clearly put a lot of work into this pigment, it'd be a…

Yeah, I don't ever recall seeing something that made me think Trump was in the pocket of "Big Pigment."

This is an area that I know absolutely nothing about, so the notion that new pigments are being created is fascinating to me. I’ve never really considered pigments and the chemicals used to make all of these colors.

Consider getting the book "The Secret Lives of Colors." The book itself is a beautiful object and the contents are a great dive in to the history and chemistry of pigment and color. https://g.co/kgs/Np4PF6

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…

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

Yes, just another few elements to leak into environment, rivers, oceans.

It does not matter if the chemical compound is inert or not, the elements will be well incorporated into a new vector of nature.

Why does that matter? The point is you can combine elements and create compounds that are drastically different to the components with different properties.

Obvious one is water. H - explody. O2 - burny. H2O - puts out fires, quenches your thirst, no longer a gas, not very reactive.

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

I was on the release event of those cards. All of that setup just for the punchline in the end: ”The first non-toxic blue”

The fact that it was said makes the amusement value even greater.
