The paint I used WAS going to be a mixture of ASCP Louis Blue, Paris Gray and Graphite, but I ran out of Graphite. Hm. What can I do to darken this color? Well, I have some black chalk board paint. What the heck, let’s give it a go and see what happens. Guess what? It worked brilliantly. I mixed in some of the black chalk board paint and it still had great adhesion and distressed well. Who knew?
