First of all, not a math question
Seccond of all, It probably means you are a sheep that is purple...
but it coud have some deep metaphorical meaning that is beyond the bounds of my perception.
I know the phrase "Black sheep" means that you are the odd one out of the group
EXAMPLE"In a family of straight A students, my low grades made me a black sheep"
so "purple sheep" could mean that you are different from everybody else, like black sheep.
The colour purple however, implies beauty and royalty (Purple symbolises royalty in european countries because purple dye was expensive, and therefore only royals could afford it.)
So being a purple sheep imlies that you are different in a beautiful/ kingly way.
This is a wonderful name choice, with positive implications towards you.
Good name choice ;)
