...do you even know what they're for? Or are you just doing what everyone is doing?
White ones are meant for community members and anyone can get them as a sign of support for the edmDistrict.
Yellow, Blue and Red are meant for people who are actually partnered with edmDistrict (which you have to apply for).
Yellow - promoters
Blue - "brand ambasadors", basically the main guys in charge of the edmDistrict and the original people that organised the whole thing
Red - producers and labels
