`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. `airbrush_replacement_node`: The node to swap in when the airbrush is used on this node.

**`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.
