User blog comment:Lilyshirogane2201/Why Aikatsu and Aikatsu Stars characters didn't have their own lightstick colours?/@comment-27055164-20180307041740

I’m my opinion the head piece in the Original Aikatsu was more similar to the glow sticks they had the idols color. In Aikatsu Stars, the people that were watching online would show up as the Idoli Color as well.
