the color circle based on the original 4. Black and white are
used only to change the original yellow, red, blue, and green

is a vertical section cut through the sphere. The "vertical
center core"
is the gray scale divided in units of "10"- from white
(at the top) to black (at the bottom). This core becomes the spine
of the triangle.
This
is the horizontal section through the center where the four chromatic
elementary colors are placed like a compass. The measured steps
in each quadrant between any two elementary colors are visually
divided and numbered in units of 10. For example, when moving
from Yellow to Red, each step gets 10% RED. Orange is Y50R since
it is half-way
between YELLOW and RED.
