How to be able to set custom values from lcd to control neopixel

Hello,

I am trying to figure out how to add custom lights control from the lcd menu of my printer. I am using a Fysetc mini 12864 lcd with RGB. Basically, I would like to be able to change the Red/Green/Blue values from the lcd menu and customize the colors of my screen. I think that the printscreen below illustrates what I would like to achieve.

I also attached my cfg file. Grateful if you can provide some guidance.
