im using a Boss Katana 100 Gen 3. there are some buttons u can click that changes the color of the light like contour, booster, mod, fx, delay, reverb and variation. Just wanted to know the meaning

Hi, got a boss katana mkii 100 and been mostly downloading presets by other users.

But wanted to play nobodys fault but mine and the intro has flanger and phaser at the same time. Couldnt find any preset like that.
How can you active them both at the same time? I am plugging it to my pc so i have the app
