This mods adds colored variants of many blocks, that can be obtained by crafting the base block with a dye. Colored blocks can be crafted back into their base block. There is also a special crafting table that allows crafting colored blocks without consuming dyes.
Blocks that have slabs, stairs, walls, fences, and fence gates also have colored versions of those blocks.
Suggestions for more colored blocks to add are welcome (Suggestions go under the issue tab)! (Seriously, it probably isn't that much effort to add the block you want, just tell me)
Please post issues under the issues tab, not in the comments.
