I have been using Natural Earth Paints whenever I can over the last few months. I know that not every color I am used to is in the range, and there is something comforting in that. I am back to mixing more regularly, which I LOVE. Convenience colors were perhaps too convenient. I think mixing from these 20 colors is a benefit to me, and it makes me feel good while I'm working to know that most of my colors are not petroleum derived.
As I use the other brands of paint that I still have, I am finding that they mix great (waste not), but I could see myself shifting to more and more of the Natural earth paints for the fixability and viscosity. They are great with a brush or with a knife (though I do use a little modeling paste at times to make them even more dense). Straight out of the tube they are soft, like an oil paint. And every time I wash a brush I think just a little about microplastics in the water, so now I feel like a part of the change I'm looking to see.
