Angles and Bar, egg tempera on calfskin parchment, 9 x 6 1/2 in.
What interested me in this image was the concentration of small angled forms at the top contrasted with the large simpler space below. And then their were the holes: an ellipse at the top and three descending circles, adding accents to the yellows.

It's always a juggling act to get the color balanced and the light believable. Warmer/cooler, lighter/darker: I often have to repaint areas several times. Because egg tempera is translucent, the repainting is easier than with opaque oil paint. The layering of color adds depth, a depth the Old Masters knew how to achieve with their glazing techniques in oil, but few of us use now. People tend to think egg tempera is a finicky medium, but I find it very easy and forgiving; and full of light.
