The group has posted on their Facebook about their official fan slogan. 
What started out to be a joke amongst KAACHI haters, it became real. 
Allegedly, it’s called “I rainbow you” because the ROSEGOLD members are LGBT and rainbow represents equality amongst people of different races, genders, sexualities, religions, and skin color. 
“We want our fans to feel included.” Aisha, the leader of the group, said about the slogan. 
Also, Aisha ships herself with Jin from BTS and Lisa from BLACKPINK and wants to photoshop herself in both of the photos so her fake ship comes true. Allegedly, the ship is called AishaJinManoban.
