BeaconPalette

This mod simply adds several objects to help players create beacon beams of specific colors according to the vanilla beam color mix logic

we add a new item called glass plate, which can be stained in the stainer block, and then inserted into the glass plate container block to modify the beam's color. The container block can be seen as a 5 in 1 glass block

The most powerful thing is, the stainer can tell you how to get the color you want(as close as possible)
