Suppose I set the white light at 20 and then I turn on yellow light to 10. What I want to ask is when I turn on the yellow light, does white light decrease, like, it will reduce to 10 (without me knowing it, because the bar value doesn't change)? If the white light doesn't decrease when the yellow light on, the screen will be brighter, theoretically, right?
