Simfphys Light Color Tool
if it does not work then this is very sad
Pick a color and left click on a headlight or somethin.
Change the area slider to make your selection area bigger.
Some more settings may be added later.
will never have duplicator support
This tool changes the already spawned/existing sprites and lamp colors based on where you click. That means it would be incredibly hard to make it support any dupes.
If a player joins in late they will not see any preexisting or changed colors.
this addon is literally the worst idea to add to a server other than a small group of friends
