This is an example of the combination of two vertical sequences—the
sequence of Red and the sequence of Yellow. I have not found
the sequences of this type very interesting. In using them in
Representation I have found it desirable to have the intensities
increase gradually toward white, or, what amounts to the same thing,
to have each color neutralized as it loses light. That happens,
constantly, in Nature.

Horizontal, or even more than two, may be combined and used together.
