From Sam/Astro on the Stellar Twinkle Chat Room:
Ok so someone pointed something out to me in the discord
Each dress isn’t white. Each dress is a different colour. The 10 Sephiroth are all represented by different colours.
I’ve added the image from the teaser video here for your reference – you can see the slight color differences in the members’ dresses if you look carefully.
Keter, the first one, is represented by white and is the start of the creation story.
Gayoung represents Keter
Her dress is white, she was the first teaser
Next is light blue Chokmah, which will be Hyoeun.
Next is Binah, which is Crimson however it can be substituted for a grey flecked pink, therefore Minhee.
Chesed is violet, so that will be Jeonyul
Geburah is orange but I believe that will be Soyoung anyways.
However since this is a comeback that features duality, will the girls also represent the next 5 steps of the Sephirot Tree?
Also I could be wrong about that initial thing and they could all just be representing one particular step of the Sephiroth.
Yeah, the Qlipoth.
That is one interpretation but the other interpretation is the dark side represents the Archangels represented by each tier of the Sephiroth
If they do they may be disregarding the idea of going in chronological order with the Sephirot.
The thing with this comeback is that it can be interpreted so broadly in such a variety of ways that seeking out the meaning for all the symbolism is quite difficult.
