The recipes

Twenty five crafting table recipes, all shapeless. Between them a player can reach every block in the pack from oak and a dye, with no operator involved.

Colouring oak

Fifteen recipes, three per family. Each takes a vanilla oak block and the dye for that family, and gives back one coloured equivalent.

Family	Dye	From oak log	From stripped oak log	From oak planks
Redwood	RED_DYE	Redwood Log	Redwood Stripped Log	Redwood Planks
Goldwood	YELLOW_DYE	Goldwood Log	Goldwood Stripped Log	Goldwood Planks
Greenwood	GREEN_DYE	Greenwood Log	Greenwood Stripped Log	Greenwood Planks
Bluewood	BLUE_DYE	Bluewood Log	Bluewood Stripped Log	Bluewood Planks
Purplewood	PURPLE_DYE	Purplewood Log	Purplewood Stripped Log	Purplewood Planks

So one oak log plus one red dye, anywhere in the grid, gives one Redwood Log.

Logs into planks

Ten recipes, two per family. A coloured log or a coloured stripped log gives four planks of the same family, the same ratio vanilla uses.

embercraft_chromawood:redwood_log          ->  4x embercraft_chromawood:redwood_planks
embercraft_chromawood:redwood_stripped_log ->  4x embercraft_chromawood:redwood_planks

The same pair exists for Goldwood, Greenwood, Bluewood and Purplewood.

Turning recipes off

Every recipe is a named entry in contents/embercraft_chromawood/configs/recipes.yml with its own enabled flag. Set one to false and restart to remove it while leaving the block itself craftable by other routes, or obtainable only through /iaget and the menu.

dye_redwood_log:
  enabled: false

That is the lever to pull if you would rather sell Chromawood through a shop than let players dye their own. Turn off the fifteen dye recipes and the pack becomes a shop-only cosmetic set, with the plank conversions still working for anyone who bought a log.
