Why not use white in our chart? Because white is incandescence in the
highest degree. We say of iron that it is at a red or a white heat. But
in this world it is rare to see a heart at a white heat. Earthly
thermometers do not mark this degree of heat.

It cannot be denied that red, yellow and blue are the three elementary
colors, whose union gives birth to all the varieties that delight our
eyes. We have proof of this in one of nature's most beautiful
phenomena--the rainbow.

The rainbow is composed of seven colors. Here we distinguish the red,
yellow and blue in all their purity; then from the fusion of these three
primary colors, we have violet, orange, green and indigo.

This is the order in which the seven colors of the rainbow appear to
us:

Violet (_red_}, orange (_yellow_), green (_blue_), indigo. Orange is
composed of yellow and red. Yellow mixed with blue, produces green. Blue
when saturated, becomes indigo. Upon closer investigation, we may easily
find the nine shades which correspond perfectly to the nine operations
of our faculties, and to the nine functions of angelic minds.

By complicating and blending the mixture of these colors, we shall have
all the tints that make nature so delightful a paradise.

The seven notes of music sound in accord with the seven colors of the
rainbow. There is a brotherhood between the seven notes and the seven
colors.

The voice-apparatus, with that of speech and gesture, is for the orator
a pallet like that upon which the painter prepares and blends those
colors which, under the brush of a Raphael, would at once glow forth in
a masterpiece.

Delsarte's criterion is true; still more, it is beautiful, especially so
with its brilliant adornment of the colors of the rainbow.

We verify our judgment by an explanation of the colored chart.

As may be seen, this chart is an exact reproduction of the criterion
explained at the beginning of this book, only we have adorned it with
colors analogous to the different states of the soul that art is called
upon to reproduce.

Beginning with the three transverse columns corresponding to the
_genus_, we have painted the lower column red, the middle column yellow,
and the upper one blue. These are the three colors that symbolize the
life, soul and mind, as well as the genera.

Passing to the vertical columns which correspond to species, we have
painted the first column red, the second yellow, and the third blue,
passing f
