ColorVeil is a tiny portable tool which places a colour filter over your screen to reduce brightness and, maybe, eye strain.

Right-click the program's system tray icon and a settings dialog appears when you can choose your preferred shade and opacity, or allow ColorVeil to select something randomly.

Once it's running, the filter will affect the desktop, videos and most regular applications (though maybe not games).

If ColorVeil gets in the way at some point - you're editing images, perhaps, and need to see colours as they really are - then left-clicking its system tray icon toggles the effect off, and on again.

There's also a "Stealth" option to hide the program from the taskbar. Run it on someone else's PC and you can leave them wondering why their screen is so much greener than it was yesterday.
