[Other Question] Help Customizing Trainer Transitions?

[xXbrendanhoennXx]

Hey all, so I've run across a problem when customizing battle transitions in the SunMoon folder. I am able to customize the entirety of the backgrounds, but I cannot figure out how to change the color of the space behind the trainer sprite. It's hard to explain without visuals so I'll just provide an attachment

This is the "Digital" transition that I went in and changed the colors to pink, because I'm just using Erika as a placeholder for a Fairy-Type gym leader at the moment, as you can see here

But I cannot find anything that would allow me to change the green color behind the trainer sprite.
I'm aware it's annoying when people ask questions without trying on their own, or without doing research, so I promise I really tried my best and have had no luck. I hope this isn't a dumb question :/

However, any help would be greatly appreciated:))
