must be deranged to suit the order of them in point of illumination ; for it
is by the latter rule a painter should dispose them in a picture: but still
there is a difficulty, owing to red and blue coming next one another, as
being equal in brilliancy, and yet they are such opposite colours they never
will harmonise together, but require the intervention of another colour.
Green would answer the purpose, but I prefer inverting the order of them,
and placing violet next the red,, which will, on the whole, have a better
effect; for green coming last, serves, in some measure, as a balance to
yellow, the first and principal colour after white; < and the violet being
blended * with the red, and partaking of its brilliancy and warmth, an-
swers better, in point of illumination, than the mixture of red with either
blue or green.
This alteration is simply no more than joining the two extremes of the
Prismatic Spectrum, which, from the almost opposite degrees of strength
in red and violet, seems a contradiction to what is right; but we shall
see how it will answer in practice, and by this arrangement they will stand
thus:—

by that means form intermediate tints.
f I would not wish it to be thought, that I consider my own opinion of this arrangement as deci-
sive, but as a matter that requires the investigation and sanction of other practitioners in the art j though
it appears the best to me, at present, as the extremities of the coloured Spectrum, on the violet side,
incline to red.
