Night Mode
Your NOOK GlowLight 3 comes with the new Night Mode for comfortable reading. With Night mode on, you can adjust
the color of the light from cool to warm. A warmer tone will reduce blue light emission for nighttime reading.
You can set Night Mode in Auto mode or in Manual mode. In Auto mode, GlowLight will automatically adjust the color
throughout the day. In manual mode, you can select the color you want on a slider.
Note that brightness and color are two separate controls.
