If anyone know how to edit aFunkyShirt addon
Yes, I do know how to edit it. And I will help you with editing it, but not do it myself. Also have the schedule set to 1000 is one second.
If you notice on the add-on it has four numbers that are probable less than 1, with the exception of the last number. This is RGBA format, being Red, Green, Blue, Alpha. Alpha is transparency, so for pure red, you would have
1 0 0 1 as the numbers. Blue is
0 0 1 1 green
0 1 0 1 yellow
1 1 0 1
