Mix or Glaze?
What began as an experiment in glazing various earths against green earth quickly turned to an obscene mess of a chart and already in the rubbish. Okay, that's what learning is all about. I gain most from my mistakes.
So rather than glaze I decided to push the blueish leaning green earth around, mixing with a yellow and a red ochre. Obviously there weren't going to be any high chroma colors but how many greens really are that screamingly intense green any way?
With yellow, the greens pulled nicely warm. Same for the red.
Now to the question that's been gnawing at me for some time. Mixing versus glazing. Egg tempera is about glazing. It loves to be glazed. Twenty (or forty for that matter) layers a day is easy. It hums with depth and luminance. Can I get the same color in glazes that I can in mixes? And vice versa?
The first two rows of stripes are mixes. Just quick mixes: top with yellow; next with red. I left out plenty of gradation. The last row is glazed. Gradated yellow or red. As I glazed along I occasionally dropped on another layer of green earth. There are something like twenty layers at the top of each stripe. (The stripe in the middle is the pure green earth control.)
I guess I've always gone on the assumption that mix and glaze can provide the same result, at least as far as base color is concerned. And, I think there's a fine richness that achieved only with glazes. I wonder... Would there ever be occasions when I wouldn't be able to mix or glaze to achieve the same base color? Is it dependent on the medium?
