In this sequence, as in the one previously given, the colors are taken
at the interval of the second.
148. The colors in these diagonal sequences may be taken not only at
intervals of the second, but at intervals of the third, the fourth, the
fifth, the sixth, and the seventh. Taking the colors at these different
intervals we have, for each interval, twenty-four distinct sequences;
twelve for the Right Mode, twelve for the Left Mode; in all one hundred
and forty-four different sequences.
149. Among the sequences of the Diagonal those in which the colors are
taken at the interval of the fifth are particularly interesting. The
colors taken at the interval of the fifth fall into four triads,—the
first, R-Y-B, the second, RO-YG-BV, the third, O-G-V, the fourth,
OY-GB-VR. Taking the colors in any of these triads in the two modes,
the Right and the Left, we get six sequences of different colors in
different values for each triad. Of these Triad-Sequences I will give
one as an example.
