It seems the article you're talking about is the opponent color process, which here's some great articles about it: https://www.handprint.com/HP/WCL/color2.html https://blog.asmartbear.com/color-wheels.html

I had some fun modeling the color space in 3d on codepen: https://codepen.io/torleifw/pen/jOwjPxp

(or a more boring slider option here: https://codepen.io/torleifw/pen/OJgdyPJ)

One of latest papers I've read recommended using a matrix to transform color spaces, which i've also done a codepen for.

Interestingly the opponent process mirrors the LAB color space, which is soon going to be available in Safari. This is pretty cool and can enable developers to color coordinate easier.

I'm going to give the webpage you linked a good read, looks very interesting.
