no never. i once bought a bottle of contradiction pure parfum on ebay, half an ounce for 15 dollars! i have my suspicions about whether it's real or not but it smells fantastic. i'm not sure if the seller is still there though, that might be a bad sign . . .
but no i have no idea why yours is bad. maybe it's a fake or maybe it was somehow messed up by intense heat. if your parfum is pale htere must be something wrong, the parfum i have is a very deep orange-amber color
