TABLE OF percentages OF COMPONENT COLORS IN THE
CONNECTING HUES OF THE CHROMATIC SCALE.

The following table shows the relative percentages,
in color-wheel measurement, of the two components in
each of the hues connecting adjacent pairs of the six
spectrum colors as represented on the original Plates of
this work; together with an equal number of exact inter¬
mediates (not shown on the Plates), the latter in lower¬
case type and not indicated by symbols.
