Your graphics driver is broken, which means the R and B channels are swapped. You're also using Windows 7, which we don't support anymore: it's only with Windows 7 that there are still drivers with this bug. Please update to a newer version of Windows or Linux.

How solve problem in older Krita versions which support Windows 7?
looks like Windows 7 has nothing to do with it. This can happen in Windows 10 too, based on https://www.reddit.com/r/krita/comments/c2je5y/does_anyone_have_a_fix_for_this_inverse_color_bug/
Gimp doesn't use the gpu, so gimp isn't affected. You can disable canvas acceleration in Krita to work around the problem, but you will miss some functionality.
For a quick fix, change from ANGLE (DirectX) to OpenGL or the other way around in Configure Krita -> Display. That will allow you to still use Canvas Acceleration and won't slow down Krita as much as not using any acceleration. You can also update your graphics card driver, and if it doesn't help, write to the manufacturer that either their ANGLE or OpenGL (I don't remember which is more often at fault) driver is incorrect in regard to color channels.

I understand that the questions are not the right place .. but who could help me =( thank you
No, your Windows is too old. We don't support Windows 7 anymore.
(In reply to Halla Rempt from comment #7) > No, your Windows is too old. We don't support Windows 7 anymore. what to do if I update windows and the error is the same? example: https://www.reddit.com/r/krita/comments/c2je5y/does_anyone_have_a_fix_for_this_inverse_color_bug/
someone in support believes that the problem is not on the side of ATI/AMD https://i2.paste.pics/203d10ca8e73d0adbeff7251378a2170.png is it possible to somehow confirm that the problem is on their side? What if >>This issue could be caused due to driver conflict, registry corruption etc.
