Dear @Mugen87 @makc3d thanks again for your reply and explanation. I have already asked the question about vertex color in InstanceMesh at [PerVertexColor](https://discourse.threejs.org/t/create-circular-planar-elements-from-points/12981/2) which works for a **same** geometry but with different color, but I do not posses enough experience in OpenGL/WebGL to come up with a shader which is needed to accomodate attributes such as different faces/vertices. ☹
