Some more of my long lost notes….
Underpainting – an underpainting stimulates imagination . A black and white canvas is tedious and arouses very little initiative
Pigments for underpainting require little oil . It’s best to underpaint in neutral colors, grays or pinks.
For grays – use white lead and umber and prussian blue
For pinks – use white lead and venetian red
A midtone surface gives more flexibility than white as both dark and light will show up.
Thin color (glaze) is used for shadowand thick paint is used for highlights.
1. “basic” (caucasian) – equal parts burnt sienna & white
2. Add to ‘basic’ skin color for darker tones and variations – raw umber, cadmium red, alizarin crimson, cadmium yellow, lemon yellow ultramarine blue
3. for lighter white tones – white + burnt sienna & raw umber
+ cadmium red, burnt sienna
+ alizarin crimson & burnt sienna
+ burnt sienna & cadmium yellow
+ burnt sienna & lemon yellow
+ burnt sienna & ultramarine
