or what you think would look good
I think they might go something like the globe in Forever
Or the girls' emblems (the star, the crescent moon, the heart, the butterfly).
Also when they were asked about Aespa's color everyone said something
Ningning, Winter: Purple
Karina: Blue
Giselle: Black
so they might have the combination of the three and have the nightsky color scheme
it seems fitting for their concept and themes
