Mission 12 - Night Light
Mild Solution
The remix gives another level for the night light.
If very bright - display a picture (like the house)
If just below room light - display a picture (like the
   happy face) and use the night light math
If dark - display a picture (like asleep) and set 
   the pixels a light sleeping color and brightness
