Can all the colours of light that we can observe and distinguish as different colours of light - except white (a mix of all visible wavelengths), black (the absence of any visible wavelength) and greys (? - I'm guessing they're a mixture of black and white, though how it works I'd love to hear, seeing as white is presence of all wavelengths and black is absence of all wavelengths) - be described by specific wavelength (or frequencies) of the photons involved in light of that colour? If I pick a random object (which is not white, black or grey) and tried to describe its colour, would there be a wavelength of light which exactly represents that colour, or is the colour a mixture of wavelengths?
