colour, in its deep state, can never be made a principle of. But by a mixture
of white you may bring it forward in a certain degree, and it is in that state
I shall speak of it, Its contrasting tint is orange, subdued by black and
white, so as neither to be too dark nor too bright for the blue.
*o*
Its harmonising tint a deeper blue.
The reflected tint is made of the pale blue, and a small portion of the
contrasting tint.
Whatever green you have occasion to admit must be carefully subdued
by black, to prevent it being too powerful for the blue.

. Fkom what has been said of the foregoing colour, it is scarcely necessary
to observe, that this colour cannot form a composition of itself.
COMPOSITION OF VIOLET.
This colour in its deepest state is unfit also for a principle in composition,
and its proper place is in the shade. But as three of the prismatic colours,
in their gradations from one to another, form each of them a third ;—for
instance, red graduating to yellow produces orange ; and yellow graduating
towards blue produces green; blue graduating towards violet produces in*
digo;—so does violet, the extreme of one end of the prismatic spectrum,
graduating towards red, the extreme at the other end, produce in its grada-
