Scarlet Dye (an example of a dye bottle)
Colors can be made using Dye Bottles, which can paint any Cement Blocks, Cotton Blocks, Cotton Felts, Lucid Glass Blocks, Lucid Glass Panes, and Lucid Hard Glass Blocks after any of them are right-clicked or tapped while being held. The Dye Bottles with the primary colors can be crafted with a Small Glass Bottle and a material associated with the color, such as Cherries being used to craft Scarlet Dye Bottles. Other secondary or tertiary colors are made by mixing Dye Bottles on a Palette Stand. A list of these crafting recipes and mixes can be found here.
