-- Colored Wood mod by Vanessa Ezekowitz
-- based on my unifieddyes template.
--
-- License:  WTFPL
--
-- This mod provides 89 colors of wood, fences, and sticks, and enough
-- cross-compatible recipes to make everything fit together naturally.
--
-- Colored wood is created by placing a regular wood block on the ground
-- and then right-clicking on it with some dye.
-- All materials are flammable and can be used as fuel.
--
-- Hues are on a 30 degree spacing starting at red = 0 degrees.
-- "s50" in a file/item name means "saturation: 50%".
-- Texture brightness levels for the colors are 100%, 66% ("medium"),
-- and 33% ("dark").
