How to bring up the Windows splash screen and change the color?

Question

Java

Hi all.
The task is to change the color of the monitor to a specific one through Java. Let's say red.
I understand that it is necessary to call the Windows splash screen (initially black) and then change the color, but I do not know what command can do this.
Got a team

Runtime.getRuntime().exec(new String[]{"scrnsave.scr","/s","start"});}

Which causes a black screen (Screensaver is visible)
If this is the correct command, then how to make this screensaver be red?

Answer 1

scrnsave.scr is a regular EXE that creates a borderless window that fills the screen (but the window is not maximized) and draws whatever it wants. With this window size, Windows itself hides the taskbar and everything else.
The same can be done in Java without calling third-party utilities. Or look for the program scrnsave-red/blue/green/girls.scr
