To give your bow an arrow trail, first craft a bow painter with a stick, string, and wool, then craft your bow with that and some dyes to set the color. If you ever want to get rid of the colors, or start the coloring over, just right click the bow on a filled cauldron. Bow Painter

It should work with most custom bows added by mods too. There are also some special particles, which you can get by crafting with these items instead of dyes. Try them out and see what they do!
