I teach colour use in a design school. The most important point TFA makes is to understand colour in terms of HSL. This is the perfect 'thinking space' of colour.
The next point key point it makes is to visualise hue on the colour wheel, particularity with reference to their antagonist pair (i.e. complementary). One point the author does not make is that artists, designers and Adobe Color define complementaries using the RYB colour wheel not the RGB. The complementaries defined by RYB are 'incorrect' in this regard.
Aesthetic arrangement of hue is easier to define as a set of don'ts rather than dos (which is why I disprove of Adobe color). Thing to avoid with hue use: hues from only one side of the wheel, hues from every point in the wheel and hues from equal sides of two halves of the wheel.
