 If your colored node is based on someone else's neutral node, for example if you made a mod that creates multiple colors of minetest_game's default clay, you may find it best to create a single "stand-in" node that's identical to the neutral node, but named for your mod, hidden from the creative inventory, and has a properly-prepared grayscale texture image in addition to the above keys.  Use the neutral node and the custom hidden node as in the above craft helper call.  Then use minetest.override_item() to add the on_construct and palette keys and the ud_param2_colorable group to that "someone else's" node.
 
 * You will need to write a run-only-once LBM to convert your old statically-colored nodes to use hardware coloring.  See above for functions that will help reduce the work required for this part.

+If your mod has no colorable items, and you wish to expand it accordingly, follow the above "never used" section, skipping the "remove/delete this and that" items, and of course omitting the LBM.
