3D widgets have wrong colors

I want my game to be in lit view mode.

However,the colors of 3D widgets look odd.

The colors only look correct in unlit view mode.

I am sure the material itself of the widgets is unlit.

How can I make it correct in lit view mode?

Some postprocessing features can change colors in scene, even if they on unlit materials. Exposure and other color grading features.

But there are so many parameters to play around in postprocessing settings.
I wonder what exact values of those parameters are while in unlit viewmode.
