Maxwell’s triangle is formed from
three parameters, x,y,z that correlate
to the three RGB vectors to determine
any color within the triangle.
But using three vectors to define a
two dimensional space is redundant.
So let’s eliminate one.
Here is Maxwell’s triangle plotted as
Right triangle based on two vectors,
X and Y.
What happened to z?
It’s not needed since x + y + z =1, or,
red + blue + green = white.
X and Y are a new vector basis system
Created by a mathematical conversion
of x, y, and z.
