This is an example of reverse painting the Mexican Agate material I used. In this photo the blank on the left was back painted with white and I believe it basically washed out the colors. The blank on the right, the lower half was painted with a red/brown mixture paint. Sort of like a muddy brown, but I did not like that either. I chose to use blue metallic spray paint and the example is the top side of the blank on the right. Maybe this can help someone if they check in here.
