It's a natural chemical element that needs smelting to get a puried metal element , it's usually a silver-gray color, but it's not easy to mix it yourself in the basement of.......oh you mean the paint! DUH!!!!
I've always bought cobalt blue as a color. It's a primary color so you aren't able to mix it.
If you want to make a color like cobalt blue, purchase ultramarine blue and buy a separate tube of turquoise blue. When you mix these colors correctly, the paint turns a bright cobalt blue
Why try to mix it when you can buy the exact color in a tube?
@astardrifter Plein Air where you gota go with what you got.
Not sure. My favorite color, though.
Especially in glass.
What kind of question is that? Are you trying to separate out one color from the rest? Is it us vs. cobalt blue, now? Aren't we divided enough as a country without this forum becoming divided?
I hope you know I'm just kidding. I think my brain went to sleep and my body doesn't know it.
