Guido is my first attempt at using black gesso (gesso is the primer). I really liked working with the Burnt Umber gesso that I have been playing with over the past few months, so I thought it would be worth giving black a try. Plus I ran out of the burnt umber, and it is only available in store at Opus Art Store - something that doesn't happen much in my world. I was a bit worried at first that it might be too harsh - but I'm thrilled with the results. I love how the owl just seems to "pop" and I think the green looks fantastic against the dark background.
