The RGB3 Color Wheel
There are three secondary colors on the wheel that are produced when primary colors are mixed:
The transition steps in between the primary and secondary colors are what make up the tertiary colors and are named as follow:
Each tertiary color is divided into four sub-categories as seen in the color wheel.
The primary and secondary colors are represented by the beginning letter of their name:
Tertiary colors are made from a combination of primary and secondary colors. The notation for the tertiary color is the combination of the two beginning letters of the colors they are made of. For example, Red (R) and Yellow (Y) produces the tertiary Red-Yellow.
Expanded RGB3 Notation System
The colors of the RGB color cube can be mapped within consistent patterns related to a gray scale and to the level of purity of the color as shown below:
The RGB3 gray scale has 6 even steps from black to white. The intensity of a color increases from left to right towards its pure state.
Each color can be mapped according to the family it belongs to (i.e. red, blue...), its relation to the gray scale, and its level of intensity.
For example the notation Y 8/4 means:
Similarly the notation Y 5/10 means:
below provides a visual summary of
Note: Compare the three notation system below. The perceptual notation (PN) system has the potential to pinpoint the color family, its relationship to the gray scale, and its level of purity (intensity):
