/cgl/ - Cosplay & EGL

I'm trying to buy these shorts in mint (https://item.taobao.com/item.htm?id=530409900524)), but the options only say "red, black, purple, blue". I figured the mint ones must be "blue", so I told my SS that (and that I wanted the mint green ones in the picture), but the store sent the dark blue/purple ones. Am I missing something? I'll try to buy them from a different store, but this still left me confused.
