My favorite color is purple, do you have a favorite color?
I like blue, and purple is halfway between blue and red!
Oh that's true, do you know what wavelengths purple occurs in?
It does not have wavelength, but is a composite color.
Oh interesting, do you know any kind of uses purple had in history?
I know that it was worn by Roman magistrates and rulers.
Oh so it was like a status symbol maybe, I guess purple was expensive and hard to obtain perhaps.
