In Minecraft, you can make orange dye using two ingredients: red and yellow dye.
First, you will need to craft the red dye by combining rose red (crafted from four roses) with an appropriate ingredient like bone meal, ink sac, or cocoa beans (all three ingredients can be found or crafted from flowers) to create four red dye.
Second, you will need to craft the yellow dye by combining dandelions or sunflowers with an appropriate ingredient like bone meal, ink sac, or cocoa beans (all three ingredients can be found or crafted from flowers) to create four yellow dye.
Finally, you will need to combine both of these ingredients in the crafting table to make a single piece of orange dye. This recipe requires one red dye and one yellow dye, so you will end up with two orange dye for every four of each ingredient.
