Also, Spectral Colours are those defined wavelength of light.
False Colours are those that are a result of our eye’s/brain’s color processing.
E.g. purple is not a spectral color: there is no purple wavelength (indigo and violet are still just blue). Blue and red are at opposing ends of the spectrum and stimulate our blue and red cones which or brain interests as purple.
