Do a tutorial for rainbow vehicles.
Make a Vehicle spawn with Recolor vehicle checked.
Make events ass follows
Onactivate -> Self -> FireRelay
Then make as many of these color evnts as you want different colors and a delay time of 100 between each one. like if you wantedone that switched between RGB you'd make three of them with the delays for each one set at 100, 200, and then 300. Be sure to keep a steady delay time.
OnRelay -> Self -> Setcolor
OnRelay -> Self -> FireRelay
If we continue to follow these guidelines of a steady 100x delay time, and we had 3 different colors, this last event's delay would be 400.
Now click send on the events and click the brick once, spawn a vehicle, and you have a Rainbow colored vehicle!
