That should probably be violet, not purple. Purple is a polychromatic color created by mixing red and blue. The word purple is often misused to mean violet, possibly because many people cannot tell the difference between purple and violet. Violet can be monochromatic and is the shortest wavelength which can be seen by the average person, about 400 nanometers. It is the next higher frequency (shorter wavelength) color, from blue. For some reason, possibly having to do with the eye's lens, people do not focus well on blue or violet light. If one looks at a 'black light' (when it's on), it appears blurry.
