null points. The yellow lines will trace out a yellow and
red, or orange square.
Now, turning back to fig. 78, we see that these two
ways of naming, the one we started with and the one we
arrived at, can be combined.
By its position in the group of four squares, in fig. 77,
the null square has a relation to the yellow and to the red
directions. We can speak therefore of the red line of the
null square without confusion, meaning thereby the line
AB, fig. 81, which runs up from the
initial null point A in the figure as

drawn. The yellow line of the null
square is its lower horizontal line
AC as it is situated in the figure.
If we wish to denote the upper
yellow line BD, fig. 81, we can speak
of it as the yellow r line, meaning
the yellow line which is separated
from the primary yellow line by the red movement.
In a similar way each of the other squares has null
points, red and yellow lines. Although the yellow square
is all yellow its line CD, for instance, can be referred to as
its red line.
This nomenclature can be extended.
If the eight cubes drawn in fig. 82 are put close
together, as on the right hand of the diagram, they form
a cube, and in them, as thus arranged, a going up is
represented by adding red to the zero, or null colour, a
going away by adding yellow, a going to the right by
adding white. White is used as a colour, as a pigment,
which produces a colour change in the pigment with which
it is mixed. From whatever cube of the lower set we
start, a motion up brings us to a cube showing a change
to red, thus light yellow becomes light yellow red, or
light orange, which is called ochre. And going to the
