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, s…

Very insightful. Will be interested to know of your preferred 12 colour palette.

I use a Yellow Ochre Light, Pthalo Blue, Titanium White, Zinc White, Transparent Oxide Red (for blocking), Pthalo Green and Perylene Red :)

Although, you can just use Richard Schmid's palette, replace all the toxic junk with modern pigments and you're good to go. The thing is to stick with the palette forever for many decades so that your paintings have a cohesive harmony.

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.

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?

Organic chemistry should probably be made mandatory as part of high school science education like physics. Parent looks like Exhibit A for anti-thiomersal hysteria.

Heh.

"YInMn Blue’s appeal stems in part from its high opacity, which means you don’t need to apply much of it to get a good coating."

This! I've noticed that blue exterior house paint, even with an expensive primer, just doesn't cover very well. This stuff seems about 100 times too expensive for that application.

"Heh" is an obnoxious response, as if an organic chemistry class wouldn't teach the basics of organometallics and some of the things that make compounds more or less dangerous.

Mercury? Of course. Tooth fillings.

Just google "mercury amalgam cancer".

Correct. One reaction involving mercury would be Oxymercuration, a process that is usually covered in Organic Chemistry 1.

I live in pride of my mercury-compound amalgam. You can choose to live in fear.

"Numerous other organizations have also publicly declared the safety and effectiveness of amalgam. These include the Mayo clinic,[21] the U.S. Food and Drug Administration (FDA),[22] Health Canada,[23] Alzheimer's Association,[24] American Academy of Pediatrics,[25] Autism Society of America,[26] U.S. Environmental Protection Agency,[27] National Multiple Sclerosis Society,[28] New England Journal of Medicine,[29] International Journal of Dentistry,[30] National Council Against Health Fraud,[31] The National Institute of Dental and Craniofacial Research NIDCR,[32] American Cancer Society,[33] Lupus Foundation of America,[34] the American College of Medical Toxicology,[35] the American Academy of Clinical Toxicology"

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.
