White Screen
A full screen of pure white. Tap or press Full screen.
Quick answer: Press Full screen to fill your display with white. It is useful as a light, for photos, for cleaning dust off a screen and for checking a monitor.
Press F for full screen, Esc to leave. In a series, tap, press Space or use the arrow keys for the next colour.
Very bright full screens can be uncomfortable in a dark room. Do not look at them for long, and do not use them as a warning light on the road or a safety lamp.
How to use it

- Tap to change to warm white, gray or black.
