wasn't it confirmed that each different colorway has different sayings on the top and none repeat between colors. Since the yellows says Human Race, I saw somewhere that any other colors with Human Race are fakes.
EDIT: did the searching, apparently it's not confirmed but a source did say that the pairs shouldn't have the same sayings between different colors (at least for the retail pairs). Almost every colorway of Pharrell actually rocking them had different sayings EXCEPT 1 pic I dug up where he rocked green ones and they say Human Race. But other than that, literally every different colored pairs had different sayings.
