how do you make players customize the lighting without affecting the other players?

i was wondering if someone can help me on how to make players customize a part ( the light ) change to what colour they would like from their perspective so it won’t affect the other players while they customize their own.

Change the Lighting properties through a local script.

You can achieve this by scripting what you would like it to do in a local script. Local scripts are done locally meaning that it would only replicate on a players client and not to the server. Some methods do replicate to the server.
