This is a Fabric mod that adds new blocks that can be dyed like leather armor! These blocks allow you to build with almost any color. There are three such blocks currently: variants of concrete, wool, and shulker boxes. Chroma concrete and wool can be crafted by putting four white concrete or wool in a square, which yields four of the corresponding chroma block. Chroma shulker boxes, however, are crafted by putting a single undyed shulker box in a crafting grid, yielding one chroma shulker box. These new blocks can be crafted with dyes just like leather armor, as seen in the icon. This yields a colored variant of that block that can be used as you please.
