Real time desktop colors change like filters

[William23668 8]

Hi

Sorry was not clear at first. I need to change Windows 11 desktop colors in real time like those filters:

 

 

I think I need to change every pixel color like a GPU driver. Can Delphi do that ? where to start ? Is there a library I can use ?

 

Thanks

Thanks I added more details. I think I need to create something like a driver to change colors at real time

This surely isn't trivial.

 

I once was about to make small tool for inverting the colors of windows that did not support a "dark theme" but I never really got started with it.

It seems that you can use the (now deprecated) Magnification API to (selectively) transform colors or run filters on the whole screen (or just selected parts of it like rectangle areas or selected HWNDs): Magnification API overview (Applying Color Effects)| Microsoft Learn

 

There is also its successor, the Desktop Duplication API - Win32 apps | Microsoft Learn which I had only used for grabbing screen data, not manipulating it. So I cannot say if it's a feasible solution for manipulating the colors.

Thanks @Der schöne Günther

 

This seems similar to what I need but that hard for me

Colors for the entire desktop, including icons, taskbar, and start menu? Or change only the colors in the desktop wallpaper?
