When watching TV or binge-watching your favorite show, a dimmed backlight is a good idea. If the room is completely dark, except for the TV, your eyes get tired much faster and it can even lead to headaches or concentration problems. It is better use your smart lamps to create an atmospheric background light. The intensity should be around 20% to 25%. The lighting mood and color depends on the color scheme of your film. For comedies or dramas, a soft yellow or pink is suitable while for action movies, a dark blue is more appropriate. It gets interesting with series like Game of Thrones where the color scheme has changed over time from rather warm tones to cool, bluish tones.
