The Semi-neutral Brown As The Extreme Primaries Blue And Yellow





when either compounded or opposed, afford, though not the most perfect

harmony, yet the most pleasing consonance of the primary colours; so the

extremes, purple and orange, yield the most pleasing of the secondary

consonances. This analogy extends likewise to the extreme tertiary and

semi-neutral colours, while the mean or middle colours furnish the most

agreeable contrasts or harmonies.



In nature pure purple is not a common colour, and on the palette purple

pigments are singularly few. They lie under a peculiar disadvantage as

to apparent durability and beauty of colour, owing to the neutralizing

power of yellowness in the grounds upon which they are laid; as well as

to the general warm colour of light, and the yellow tendency of almost

all vehicles and varnishes, by which the colour of purple is subdued.



TTITLE BURNT CARMINE



is the carmine of cochineal partially charred till it resembles in

colour the purple of gold, for which, in miniature and water-painting,

it is substituted. It is a magnificent reddish purple of extreme

richness and depth, eligible in flower-painting and the shadow of

draperies. As it is generally impossible, however, to alter the nature

of a pigment by merely changing its colour, burnt carmine is scarcely

more permanent than the carmine from which it is produced. If used,

therefore, it should be in body, and not in thin washes or as a glaze.

Durable pigments are admissible in any form; but semi-stable pigments

(gamboge excepted) should only be employed in body.



TTITLE BURNT LAKE



holds the same relation to crimson lake as burnt carmine to ordinary

carmine; and is hence a weaker variety of the preceding, with less

richness, and likewise less permanence.



TTITLE INDIAN PURPLE



is prepared by precipitating an extract of cochineal with sulphate of

copper. It is a very deep-toned but rather cold and subdued purple,

neither so red nor so brilliant as burnt carmine; and is chiefly of

service in draperies. It is apt to lose its purple colour in a great

measure on exposure to light and air, and assume an inky blackness; a

defect which becomes less apparent when the pigment is used in bulk.
