different colors in game mode and editor

hello guys.
i cannot understand what has happened and my colors are so different while I edit the level (which are the colors I want to achieve) with those in the game mode.
i tried some of the solution i found here, like adding some post process volume, restart level or rebuild lighting etc. but nothing worked, it seems like the colors/light will not change no matter what i do.
can anyone suspect what is causing this?
i am attaching the screenshot to see what i mean (the lighter one is the one with the desired result.)
thank you in advance.
