be interspersed throughout, but none of them can be of a brilliant green; 
for, unless of a much lower tone than the blue, they would attract the. 
eye before it; and therefore care must be taken that neither the green 
in the leaves, nor the yellow in the flower, are made too striking, lest they 
interfere and hurt the brilliancy of the blue. The white is friendly to the 
blue, and will not diminish its lustre; but‘the blue and red must be thrown 
in very slightly; the latter by means of some accidental circumstance; and the 
black in as small a quantity as the pure white demands, to assist in the 
deepest shade, and give spirit to the whole. The reflected tint must be formed 
by a mixture of the orange, blue, green, and black being thrown into flowers 
and leaves at the extremity on the shade side, while the lighter tints may 
be given in the backs or outsides of the leaves and flowers, on all the 
surrounding parts on the light side, while the brilliancy of the colours are 
kept in the centre, or most prominent part of the group.
