Blue Scrubs vs Green Scrubs at my school book store

[borinick1492]

I was at my school book store yesterday picking up books and checking out the school supplies. They have scrubs there too. Which I honestly can't wait to purchase. However they had two kinds. Blue scrubs and green scrubs. And they had a sign that said you needed to check with your instructor/program before purchasing.

I know that you don't go to my school. But can you give me an educated guess as to why there are two colors?
