When I am doing studies after old masters, I like to think about which oil colors and pigments would have been available in the time they were working. To that end, I find myself drawn to Rublev Oil Paints, which I believe is a the paint production arm of a company called Natural Pigments. As I understand it, Natural Pigments/Rublev look at the history of the materials they use and try to recreate historically accurate pigments and paints .
Some of my favorites Rublev paints are Lead-Tin Yellow, Transparent Mummy, Minium (Red Lead), and Italian Green Umber. I also use their Lead White (which I've recently introduced into the brightest highlights of some my Bob Ross mountains).
Has anyone else used Rublev paints? What do you think of them? Do you have any favorites? They are pretty expensive so I try to choose carefully before buying and would love to hear about other people's experiences.
