Keeping with the theme of the day, the bear was first rendered in black and white, then glazed with earth colors to keep it subtle.

I've worked with glazes before, but never in this context. It was rather freeing to have the values already mapped out and only have to apply the glazes. Jeffrey Hayes is a favorite still life artist, and is one of few who start with a grisaille underpainting. He details his painting method in his blog, and it's worth the read. I'm looking forward to trying this method again, with more colorful glazes.
