You have piqued my interest, oil paints are going to be made safe for schools and I now want to know how they formulate all the colours.

From what I understand you can get many things out of crude oil but you can't just rearrange a few hydrogen, oxygen and carbon atoms to get any colour in the sRGB colour space. So what is the science of safe paints? Got to know now.

I don't know all the details, some were pretty hidden. I just looked because I saw a "non-toxic" label and doubted it.

I remember the dies that I could understand are mostly organic (and thus, may have a limited lifetime). There were many that I gave-up understanding the composition.

Anyway, I brought those in 2013. Things may have improved.
