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 coining 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 
nsmatic Spectrum, which, from the almost opposite degrees of strength 
in red and violet, seems a contradiction to what is right; but we shall
