How do I change vertex color in runtime?

Change the colors array of the mesh with Mesh.colors

Have a look in the Scripting documentation and look for the class called “Mesh”. It has a property called “colors” which contains a Color object for every vertex in the mesh. Manipulating this array will set the vertex color at runtime.
