yellow, blue, and green, which, if they form a separate mass by themselves, will 
increase the value of the more brilliant tints in the centre of the group. At 
E, black and the contrasting tint should be placed; and between them, and the 
light pinks on the centre, there should be some of a fuller hue, gradating down to 
violet, in the deepest shade; the reflected tint at F may be composed of grey, 
and a mixture of the other tints ; but one thing must be observed, viz. that 
yellow must be sparingly used throughout, and likewise the orange, as neither 
will do in a much larger proportion in this composition, than as they are seen 
in the seeds.
