Sometimes you need more colors to express your creativity, this mod adds that. By default it will add 64 shades of each color added, but there are config options to change it down to 9 shades, and up to 289 shades. Also included are stairs and slabs in all the shades and colors, there is also an option to not add stairs and slabs if you only want the full nodes.
You'll need the colorizer mod to make these nodes. You can find it here.
