My biggest disappointment with the new Macbook Pro is that it didn't include tunable color temperature for the keyboard. For an iPad, just changing the screen works because that's all it is. When your keyboard is a separate glowing thing, having your screen at 2200K and keys at 6500K looks awful. I used to turn the backlit keys off while running f.lux, but you're stuck with a touch bar at minimum now.

Oh well.

EDIT: Obviously the touch bar is full color and could be shifted like the screen. But because Apple's stance is that it's part of the keyboard, and the keyboard can't shift, I don't think they will. Curious if anyone's tested it though.
