If your node if of the kind where you need the split palette, but you need to put the *full color name* into the node name, as opposed to just the hue, then add the keys `ud_color_start` and `ud_color_end` and set them to the positions of the first and last characters of the color name (where 1 is the first character of the mod name at the start of the node name, i.e. "mymod:foo_bar_orange_baz" would have the start set to 15 and the end at 20).
`on_construct`: see below.
`airbrush_replacement_node`: The node to swap in when the airbrush is used on this node. For example, you could `minetest.override_item()` on some default node to add this field, pointing to a colorable node of your own, so that when the default node is painted, it's replaced with yours in the new color.
#### Function calls

This one does just what it sounds like - it shows the color selector formspec.
**`unifieddyes.on_construct(pos)`**
This function, usually called from your node definition's `on_construct`, just sets the `palette = "ext"` metadata key for the node after it's been placed. This can then be read in an LBM to determine if this node needs to be converted from the old 89-color palette to the extended 256-color palette. Although it is good practice to call this for any node that uses the 256-color palette, it isn't actually necessary as long as the node has never used the 89-color palette, and won't be subjected to an LBM that changes its color.
**`unifieddyes.register_color_craft(recipe)`**
This will loop through all of Unified Dyes' color lists, generating one recipe for every color in the palette given in the call. Example usage:

* Add the above recipes helper call (which replaces those delted recipes)
* 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 which has a properly-prepared grayscale texture image in addition to the above keys. Use `minetest.override_item()` to add the `on_construct`, `palette`, and `airbrush_replacement_node` keys, and the `ud_param2_colorable` group, to that "someone else's" node. Then use that node and your custom, hidden node in the craft helper call.

* 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.
