Hey Reinhard,
I was surprised by the amount of highly saturated colors that are inside of these studies I've been doing lately.
I use photoshop and a tablet to paint.
Usually I'm operating kind of like In a more middle to desaturated color scheme, with usually monochromatic, or limited color variation, just cause it's easier to make a painting look better that way.
I'm just trying to learn - Thanks for the comment.
