The script works like I wanted, but whenever a player pressed the button, the ColorCorrection get enabled for all players in the game, how can I fix that this does not happen for all players but only for the person who pressed the button.
Ok so as @JarodOfOrbiter said get rid of the server script but if you still want a Remote event you have to use something else called Bindable Events it follows the same things as Remote events just for local scripts.
