Gielreta:
Actually, the spell that wounded Hermione in the DoM was purple.  I 
don't know what the spell is, but it is obviously quite dangerous.  
Also, JKR has descibed several things as violent purple, including 
one version of Tonks's hair and the Knight Bus.  Also, the both the 
curse that hit Hermione and the flames in the logic puzzle in SS were 
both described as "purple flames."  Don't know if this helps, but I 
think that purple is prevalent.
