Fixed Dye Amps

are they in any colors or specific ones?

Don't think so.

Just wondering. I just see a ton of black dyes floating a round thanks to this event.

I think they might be, I have found repeated dyes of the same color. No black ones though.

I've received 2 White and a black fixed dyes from the Prize bag. I've heard players have received neon red and green from the event bag as well.

Neon Purple can also come from the bag.

I've recieved green as well, that's all apart from the Neon Purple Bidica stated previously.
