 `recipe` is the same as in the normal call, except that Unified Dyes will replace all instances of the string "NEUTRAL_NODE" with the item specified in the preceding `neutral_node` field.  Every instance of "MAIN_DYE" will be replaced with a portion of dye, as Unified Dyes' recipe helper works through its color lists (i.e. this field will become whatever dye is needed for each recipe).
 
-`output_prefix` and `output_suffix`, if specified (must use both if at all), will cause the recipe registration to ignore the usual `output` field, and instead set to the output item to `output_prefix` + (hue) + `output_suffix`.  Used for mods that use the split 89-color palette.  `hue` will thus be one of the 12 hues, or "grey", as defined by the split palettes.

Used for mods that use the split 89-color palette.  `hue` will thus be one of the 12 hues, or "grey", as defined by the split palettes.  In this situation, you can set `output` to your recipe yield (with a leading space) if needed.  For example, if the prefix is "foo:bar", the suffix is "baz", and the output is set to " 3", then the craft helper will generate output item strings of the form "foo:bar_COLOR_baz 3", for each color in the table.
