Change the color of a part pressing a keybind?

Edit: I made it not capitalized because that was rude sorry

grrr remote events. i dont know why so many of peoples problems are caused by them not knowing what remote events are, you look up on ur browser "how to detect press", use getmouse done in 4 lines of code, then you fire a remote event and then you set up a listener and then use that listener to change the color of a part when the remote event fires from the client

pls learn remote eventsssssssss it solves 67% of ur problems i swear
