Color Theory Project 3) Johannes Itten Star

The Itten Star is a complex color wheel constructed from 12 colors, each having a pure hue, 2 tints and, 3 shades.
Within the 12 colors:

Primary colors: Red, Blue, Yellow.

Secondary colors: Purple, Orange, Green.

Tertiary colors: Red orange, red purple, blue purple, blue green, yellow green, and yellow orange.

How to achieve this : Using only the 3 primary colors (R,B,Y), mixing these 3 in different ways you create the 12 hues. In order to achieve the tints, white must be added to the hue. To achieve the shades, black must be added to the original hue.
