I decided to challenge myself to paint something with just one pigment. If you want to join me, here’s the challenge: use one pigment, and one pigment only. That means the paint you choose must be a single pigment paint. You can use water, ox gall, masking fluid, whatever, but when you are finished there can be only one thing remaining on the paper.
Mine was Daniel Smith, Cobalt Blue, (PB 28.)
Here’s how mine turned out. I’m gonna give it another shot.
