Problem With Green Hair?

St. Patrick's Day-themed pic #3...

This was based on a request from (sorry it took so long for me to get around to this)

He asked me to draw Rarity during that "Boast Busters" episode where she runs saying green hair is an awful color, running past "Negima" characters Haruna Saotome, Chisame Hasegawa, and Chachamaru (all of which have green hair in the Xebec version of the anime). But when St. Patrick's Day was coming around, it gave me an idea and came up with this pic.

Rarity's in deep crap for saying that green-colored hair is awful... and it's St. Patrick's Day... and Haruna, Chisame, and Chachamaru are about to give her a lot of pinching...
