My favorite color is purple, do you have a favorite color?
1_Wizard
I like blue, and purple is halfway between blue and red!
0_Apprentice
Oh that's true, do you know what wavelengths purple occurs in?
1_Wizard
It does not have wavelength, but is a composite color.

Oh interesting, do you know any kind of uses purple had in history?
1_Wizard
I know that it was worn by Roman magistrates and rulers.
0_Apprentice
Oh so it was like a status symbol maybe, I guess purple was expensive and hard to obtain perhaps.
1_Wizard
Yes, it was always associated with royalty and magic in Europe.

I didn't know it was associated with magic, that's pretty neat. I wonder if purple has any psychology behind it, do you know about the psychology of colors?
