Question:

What is the difference between xhromate green and regular green?

Best Answer - Chosen by Asker: One is using the pigment Chromium, which for some reason has been banned and replaced with a Napthol or invented type of pigment.

As with most artists, have a habit of licking the brush after use, or not wash their hands after using original pigment colors, would slowly poison themselves.

If by comparison, 20 30 years ago, the average age for an artist was about 45. With health issues at forum, a lot of the pigments were discarded as a safety problem solver.

The difference of the two types as you asked about, does the color move, that is does it fade after a period of time.

A pigment color is fixed

An invented pigment, has no such history, some move, then to fade or break down to the basic color inventions to fade.
