I don't know what this is, but it looks cool.

Thank you! It's just an abstract, practicing composition and color.

Hmm, I never thought of color that way before. So you're using the same one color and then sliding the saturation scale up and down to create your values?

I change the hue as well. The darkest color here is a mid saturation blue and the lightest color is a near grey orange. It's important to get a good temperature shift in the hue or relations as well. If it was all the same hue (with no greys) it would start to get pretty muddy. I'll be playing around with this more so I'll post some others when I'm happy with it and try to describe it in a little more detail.
