Composition of Broken Colors.

table showing percentages of neutral gray
in the broken color scales.

Every Plate in each series of broken colors (' to '"")
contains exactly the same percentage of neutral gray in
each color, the relative amount increasing progressively
in the several series, as shown in the following table.
The percentages of white in the tints and of black in the
shades of the tone scales are in all cases exactly the same
as in the tone scales of pure colors.

Note.—The percentages given in the preceding tables may not in all cases be pre¬
cisely those actually contained in the colors on the Plates, since absolute preci¬
sion in reproduction is hardly possible. AU that can be claimed is a reasonably
close approximation to the ideal.
