Black and white gesso experiment

Bob Burridge sometimes starts his paintings in black and white, then adds color by rubbing very wet acrylic paints on with paper towels.  It came the time I needed to gesso some canvases, so thought Id use black for a change.  Then I remembered Bobs videos and thought Id give his method a try. 

Heres the first one done with the addition of just two colors. Yellow and opera pink. I love the orange it makes.    But what about the green, you ask.... thats a Jane Davies hint.   Mix yellow with black and add white to make the greens.  Wow.   Ive been waiting to try that as well.  Kind of a dark olive. She adds much more white and gets a celedon.    I threw on the black and white striped tissue paper over the color glaze and added another light coat of glaze over top.
