I want to get colors to pop as much as possible. So I go to set the screen mode to Vivid. What should I set the white balance at and also what should I set the Red Green Blue at under advanced settings? I'm on Android 10.
Vivid is the best setting you can use. As for color and white balance, that's entirely up to YOUR preference, and it's there for a reason: panels vary. So you can change settings to how you like things, and in case your panel tends to shift towards warmer or cooler shades of white. There's no formula for that one here except for the Vivid mode and Video Enhancer mode for supported video apps.
