But I agree, a straight forward How-To would be beneficial.

Violet corresponds to the shortest visible wavelengths -- shorter than both blue and red.
The explanation is that the S/red cone cells are also activated by short wavelengths for some reason.
But humans can only perceive a three-dimensional projection of colour (red, green, & blue).
What's interesting is that it's *not* an orthogonal projection. Here's a plot of the basis vectors.
