The CE colors.

I get Gege's color blind or whatever, but why on EARTH did he and mappa not listen to the fans on some these colors dude.

Ryu's piss yellow beams made blue:

I don't mind this one THAT badly, but Yellow would've clashed with pink so much more nicely. His technique is literally focused around firing off his cursed energy, so why wouldn't it be slightly different than regular cursed energy? Also, Yellow fits this dudes design so much better compared to the blue.

(Even the finger bearer, who had no technique (did it? Eh, unimportant), had YELLOW cursed energy, and it was doing almost the same thing as Ryu, it was firing off pure cursed energy.)

Hakari's green CE made blue (with ✨sparkles✨):

This one annoys me. I know ya'll are gonna say i'm a "Stupid Tuka donka larper", but DUDE. His ONE important fight is against Kashimo, the purple lightning man. There is a reason the fans made his CE green, it clashes amazingly against purple. Also, he has a CE trait, as well as a technique focused around gambling, why not make his CE green, to mimic his whole being lucky thing?

Yuta gets a custom color:

WHY??? Does cursing someone give you pink CE???
He has no trait, his technique has nothing to do with his cursed energy, and yet he has a custom color??? It would've made sense if his cursed energy was made pink so that it would clash better with Ryu's, but that doesn't make sense now, since Ryu's lasers and CE were made blue.

(Who am I kidding, it's cause he was the original MC, and therefore gets special treatment.)

Sukuna's red CE will likely stay red: (Thankfully)

When Yuji is freaking out against the finger bearer in season 1, he starts to lose control, and accidentally taps into Sukuna's cursed energy for a moment, which is why his cursed energy is red in that scene, and blue later.

(I think this is true..? It might have been just a season 1 mistake though, like Sukuna's black cursed energy in episode 1.)
