Colored Rail Detector

This mod introduces an interesting interaction mechanic with detector rails. If you place such rails on colored blocks (wool, concrete, concrete powder, terracotta, glazed terracotta), they will only activate when the player is holding an item of the corresponding color in their main hand.

The mod is only required on the server for full functionality, but if you install it on the client as well, the features will be available in singleplayer mode.
