How to color a especific area on a mesh?

Hi, I’am trying to color a small area of a mesh, the player will click on it, than it will change the color of a tiny piece, i was trying coloring by vertices and with shaders but no success

Hello. Its not that simple.

Depends on the mesh, and in any case what you change is the material or the sprite of the material.

Look at this post.
