Lost color

[CroatianLawyer]

The color yellow has suddenly disappeared from my desktop and from all applications within my Windows 10 OS. However, when booting up my PC, prior to entering into my WIN user account, the color scheme on the lock screen seems to be OK. I updated  Intel HD Graphic 630 driver but it didn't help. Please, advise!

So the Intel support engineers can have more information about your system, Download, run, and save the results of this utility as a text file:

Then ATTACH the text file using the instructions under the reply window ( Drag and drop here or browse files to attach ).

Dear all, 

Thanks for helping me. I solved the problem. Like in many complex issues, the solution appears to be quite simple. I apparently typed Windows-Ctrl-C by mistake and changed Color Filter by that. Since some people reported the same problem on forums, the solution is: Select Start  > Settings  > Ease of Access > Color filters. and then turn color filters off.
