Hello! I'd like to introduce you to my not so compact, Redstone Beacon Color Swapper (Short R.B.C.S.). I'm fairly new to redstone so this machine isn't compact at all. Atleast it works :P. You can turn the beacon on and off with the button above the diamond block. And you can change the beacons color with the buttons above the colors of wool. If you activate a color a redstone lamp above the button wil emit light, so it's easier to see which colors are on the beacon.
