How to edit the texture of a shot arrow in Minecraft?

I know how to insert your own textures in Minecraft and use them in the game. However, I don't know how to edit the texture of an arrow that has already been shot and is stuck in a block. Anyone have an answer?

You have to find and replace the file for the texture…

At entity / arrow.png

This is how I change the texture of the arrow when I'm holding it or when it's dropped, but not the texture of the arrow when it's in a block or flying.

No that would be item / arrow
