You will need to craft a brush and paint. You can use any color of dye.
Then you need to set the paint on the ground and click it with your paint brush. You can paint 3 times and then you will need to click the paint can again. Each can of paint has 100 uses.
It also is supported by mods like myladders, myfences,mymeshnodes, mymillwork, myletters, mynumbers, mywhiteblock and more!
