This is a piece I just finished for the upcoming Fab 50 Show at The Soda Gallery in Dallas on March 1st (50 artists, 50 pieces, $50 each).
This was my first attempt at adding color to a scratchboard, and found that it's remarkably easy to to add watercolor washes to the Ampersand Claybords. The silver was also an experiment, where I masked out the black drawing with a carefully cut chunk of blue painter's tape. Spray painting the black was a total disaster, actually, because the paint wouldn't adhere over the silver layer. I ended up having to manually draw the lines and hand paint the fills. The painter's tape did a nice job of texturizing the silver when I pulled it off, which was a happy accident.
Despite my reluctance to integrate color into my drawings, generally, this was successful enough that I suspect I'll be doing more of it down the line.
