The other fascinating thing is light-fastness. PR83 (Alizarin Crimson) is a cool red (purple facing), and is recommended by many art teachers... It's also objectively shit as a pigment. It is not light-fast at all, and fades after only a few months. https://www.justpaint.org/alizarin-crimson-now-you-see-it/ Yet art teachers continue to recommend it. Nowadays most companies sell it as a 'Hue'. That is a mixture of more light-fast paints designed to emulate the original, but some companies sell 'Alizarin Crimson Genuine', which is still recommended by academics to this day. Other fugitive colors include aureolin and chrome yellow. The later of which was used by Van Gogh and has caused his paintings to fade irreversibly. https://cen.acs.org/articles/94/i5/Van-Goghs-Fading-Colors-I... |
