Member Colors[]
Each Kobushi Factory member has their own color for outfits and merchandise to distinguish between each member. On June 3, 2015, on Hello! Project Station, the founding members of Kobushi Factory and Tsubaki Factory received t-shirts revealing their official member colors. Across the two groups, their member colors were distinct, with Kobushi Factory being assigned darker colors, and Tsubaki Factory being assigned lighter colors. Upon Kobushi Factory's disbandment in 2020 and the addition of the four new Tsubaki Factory members in 2021, the colors are no longer kept distinct between the two groups.
