scale has been fixed upon as before recommended, will stand thus; of orange, 
two parts, seven tenths,* of green, six parts, and of blue, six parts; and then, 
let the size of each part be what it will, when properly combined, they will 
produce precisely the same effect as to harmony with that of the rainbow, or 
prismatic spectrum. 
It is scarcely necessary to observe, that the separate parts or portions 
of each colour, are not to be confined to one spot or space in the picture, 
but should be distributed throughout the whole group. Thus at A, I would 
place some of the orange, where the light is supposed to strike most fully 
on the group; and the rest I would distribute throughout, some in the 
shade, and some at the extremities, without apparent design. 
The darkest shade of blue, and some of the darker green leaves, should 
be disposed of at B; and some of the orange, mixed with these two colours, 
would form a reflected tint at C, and complete the dark side of the group; 
while lighter shades of these colours might be thrown into ail the surrounding 
parts, by means of the flowers and leaves being placed in different positions, 
as fancy would direct, although some little study at first would be requisite, 
before the management of the colours became easy. The eye would 
soon become accustomed to it, and there would be no occasion to have re¬ 
course to formal measure, which would only be necessary, till the eye was 
capable of judging without its assistance. 
* Of an inch, or half a one, or of any space or compass that is suitable to the purpose; 
for the size of the scale must of course depend on the size of the picture and number of colours 
introduced.
