Colour Analysis Charts by Emily Noyes Vanderpoel (1902)

Albers is great (non-dogmatic, focus on learning through practice), but ugh, Itten is such bullshit (an arbitrary system not grounded in concrete evidence about human perception). No offense, but 50% of your links are pseudoscientific nonsense.

In my opinion, the best online source about color is http://www.handprint.com/LS/CVS/color.html

The author eyeballed the sources and manually decided on an abstracted color scheme representation. (Remember, no computers in 1902.)

You could do the same thing today in a more automatic way by using by using some kind of clustering algorithm on the colors of pixels. I would recommend first applying some kind of bilateral-filter blur, then clustering the pixels (or some random sample of pixels), representing each cluster by its centroid in a roughly perceptually uniform color space (e.g. CIELAB or CIECAM02), and then apportioning squares to each cluster based on the relative number of pixels included.
