I'm sorry, but unless "purple" has a different meaning from French "violet" which is normally given as its translation, it *definitely* has an associated wavelength range. The range between 400nm and 430nm *is* perceived as purple by people, and is not a mixture of red and blue wavelengths (ranges respectively 600-700 and 450-500). If purple didn't exist as a single wavelength range, we would never be able to see it on a rainbow (since by definition the colours of the rainbow are unmixed wavelengths.) but would only get the "purple" sensation when we see a mix of red and blue lights.
