A couple notes:
• Some people have a hard time getting darks in casein because it dries matte. If you've had that issue, you can use black or try the Shiva colors—violet and green.
• They're quite transparent and can give you deep dark mixtures while still keeping some color identity.
• If you paint on illustration board or panel, you can build up some impasto texture. It generally doesn't crack or chip unless you flex the support or really abrade the surface.
• Don't worry if you can't buy casein where you live. You can use Acryla gouache or just acrylic or gouache instead. What I like about casein is that the paint is midway between gouache and acrylic in the strength of the glue-like emulsion, not too sticky or plastic-y and not too soluble after it dries.
jamesgurneyart Yes, the smell can seem sort of medical. They told me it was a preservative to keep the milk-based proteins from spoiling. To me the smell evokes old-school memories of older illustrators doing demos in the 1980s, but I know it may hit others differently.
blackbirdcd "I’ve really enjoyed casein, and I’ve used it a lot for my Space Art livestream. Usually I use casein to emulate the John Berkey style (although I haven’t made my own acrylic/casein mix like he did). The Richeson/Shiva casein is fantastic. I had okay luck varnishing casein but only after applying a layer of clear gloss acrylic.
I've been using Liquitex gloss varnish, especially for dark-keyed paintings.
lorideboerdesigns "Thanks for turning me onto casein, James! You are missing a few of Richeson's newer colors, including Naples yellow, terre verte and I believe there is also now a turquoise one. I am finding that I do need to mix my own browns, as the raw umber seems like it has a bit too much green for my taste."
You're right. My chart also seems to be missing burnt sienna.
Ultramarine blue deep, burnt sienna, Payne's grey, and Permasol blue.
