finished with the same two neutral tints, and afterwards washed
or glazed over with the colours, in the order described in the
diagram, beginning with red, then orange and yellow, in the
foreground, with blue and violet for the sky and distances. By
this process, in the middle of the picture green will prevail,
partaking more of yellow near to, and more of blue as it recedes
from the eye; still bearing in mind that all objects will partake
of their natural colour: thus a red cloak must be red, and a
green tree must be green, till its distance, or the intervening
mass of vapour (called aerial perspective) takes away colour,
and blends it with the neutral tint.
As the Plates in my former work employed a great number
of women and children in colouring them, I expect to render
the process much more easy in this present work, by the follow-
ing instructions given to the printer and colourer.
"The Plates to be printed in a bluish-grey ink (this is the
neutral tint for the light and shade of the Landscape); the
"colourer to wash in the sky with blue or violet, &c. accord-
"ing to each sketch; also going over the distances with the same
"colour; then wash the foregrounds and middle distances with
"red, orange, or yellow, copying the drawings; and when dry,
"wash over with blue, to produce the greens in the middle dis-
"tances: this heing done as a dead colouring, a few touches
with the hand of the master, and a harmonizing tint to soften
"the whole, will produce all the effect expected from a co-
loured print."
