MAKE SURE TO ONLY USE IN SINGLEPLAYER! It will not work properly otherwise (it may be possible to modify it to work in multiplayer, but don't get your hopes up).
This datapack (SHIFT_c) was originally designed for a puzzle map (which was going to be called Shift, the c stands for commands), but when I started to make the puzzles I realized I'm not clever enough to make anything good with it... but hey! Someone out there might use it! The datapack uses lime, red, and cyan dyes. To use the items, hold one in your main hand and press F. For information, visit this website (wiki?) (I strongly recommend this if you're planning on making a map with it).
