This is the fucking stupidest shit from GF that has plagued this franchise since 2013. Why the fuck would you want to make the models look exactly like the outdated artwork that was made to be viewed as a 2D drawing on paper? Fucking Electrode has suffered the worst because of this. It's been pink since 2013. The best part is that its SV menu sprite is the proper colour that it should be, making it wildly inconsistent.
Also, the B team ignores this mindset. Both LGPE and Legends: Arceus had better colours for Pokémon, such as a red Electrode, vibrant Paras/ect, and a Golduck that doesn't look like it's sick all the time. Seriously, you'd be surprised at how much difference the colours make. Golduck became one of my favourites due to Legends: Arceus, yet they made it look all washed out and shitty in SV again.
