I completely agree. As an art teacher, I am often called upon to teach 'colour theory'. Well... find me a theory in the true sense, and I will teach it. Goethe's 'Theory of Colour' is no such thing. Past that, received wisdoms like 'yellow comes forward, blue recedes', is provable bunk. The core problem is that from the very birth of colour science, the subject has attracted floppy thinking. Newton himself added an accurate colour to his colour wheel for no other reason than he thought it should correspond with the classical musical scale.
