COLOURS FOE PORTRAIT PAINTING.
COBALT
Is of a fine sky-blue colour, and the best blue pigment
for producing the silvery tints on flesh in painting in
water-colours. Alone, it forms the blue tints, and with
Indian Red, the shadow-colour for flesh. It works well
and is permanent. By artificial light it assumes a purplish
tint, which, however, is not perceptible in the flesh.
FRENCH ULTRAMARINE.
A fine blue .colour resembling Ultramarine, which by
artificial light acquires a purple tint. It is used in
draperies.
SMALT.
A vitrified pigment prepared from Cobalt, of a deep
purple blue, used sometimes for shading other blues. It
works badly, and must be stippled, not washed. It
appears of a red purple by artificial light.
INDIGO.
A vegetable pigment of a deep greenish blue. It washes
and works well, and is a useful colour for backgrounds, and
with Sepia makes a retiring green for distant trees, &c.
