nooooooo, that's depressing lol. It would be so much easier for me to show people your art if you were on there. You don't even know. I mention you a lot to people when we talk about art, my favorite artist, and the kind of art i aspire to make some day(btw don't judge my art by my devART account, it's way out of date lol). Anyway, you're awesome.
Rust and Teal are one of my favorite combinations as well. I love copper and turquoise jewelry, and I always find it funny that turquoise, which is partly made of copper, would be the opposite color of copper itself.
Anyways, I really like the use of color in these paintings, how they contrast each other as compliments and in saturation.
It's probably because oxidized copper forms verdigris, which is blue, blue-green, or green depending on what kinds of chemicals were present while it was oxidizing. If you ever see a really old building or church that has green roofing, it might be copper or bronze (which contains copper).
Oh yes, that's what turned Lady Liberty green, correct? I hadn't thought about that influencing the stone's color, but it is a great point. After I poked around on the internet, I did find that water plays a role in both the oxidization of copper as well as the formation of turquoise stone, which I hadn't known about turquoise.
