Man, they teach color wrong. Goethe is far more logical. Colors *do* come from the boundaries of light and dark and this shows it clearly.
THERE it is! Now I ‘get it’. Goethe was right. Newton missed something big about color that Goethe corrected. Look the spectrum that Newton missed, demonstrated and why you sometimes see “Red Green Blue” as primary colors and sometimes see “Cyan Magenta and Yellow” as primary colors.
Making more sense now.
