When purple helps

Purple can make some tint and uniformity issues easier to notice, especially after you have checked red and blue separately.

It can also be used as a clean full-screen color for focus, photography backgrounds or simple visual setups.

How to use it safely

Use fullscreen, keep brightness comfortable, and exit with Esc where supported. For monitor testing, compare with white, black and gray too.
