Point material vertexColors not overwriting material.color

When specifiying the vertexColors for Points the color is adding to the Material.color instead of overwriting it. Only way that material.vertexColors = THREE.VertexColors works is if material.color =“white”

///////////        I WORK      ////////////////
var starsGeometry = new THREE.BufferGeometry();

    
		var points =new Float32Array([1,1,1]);
    var Vcolor =new Float32Array([0,0,1]);
   

		starsGeometry.addAttribute('position', new THREE.BufferAttribute(points, 3));
		starsGeometry.addAttribute('color', new THREE.BufferAttribute(Vcolor, 3));
    
    var starsMaterial = new THREE.PointsMaterial( { color: 'white', vertexColors: THREE.VertexColors } );
		var starField = new THREE.Points( starsGeometry, starsMaterial );
///////////////////////////////////    I Black  /////////////////////////////////
     var starsGeometry2 = new THREE.BufferGeometry();


      var points2 =new Float32Array([2,1,1]);
      var Vcolor2 =new Float32Array([0,0,1]);
   

		starsGeometry2.addAttribute('position', new THREE.BufferAttribute(points2, 3));
		starsGeometry2.addAttribute('color', new THREE.BufferAttribute(Vcolor2, 3));
		var starsMaterial2 = new THREE.PointsMaterial( { color: 'red', vertexColors: THREE.VertexColors } );
		var starField2 = new THREE.Points( starsGeometry2, starsMaterial2 );
///////////////////////////////////    I Red   /////////////////////////////////
    var starsGeometry3 = new THREE.BufferGeometry();


      var points3 =new Float32Array([3,1,1]);
      var Vcolor3 =new Float32Array([0,0,1]);
   

		starsGeometry3.addAttribute('position', new THREE.BufferAttribute(points3, 3));
		starsGeometry3.addAttribute('color', new THREE.BufferAttribute(Vcolor3, 3));
		var starsMaterial3 = new THREE.PointsMaterial( { color: 'red' } );
		var starField3 = new THREE.Points( starsGeometry3, starsMaterial3 );

Is there a general reason for this multiplication(tinting) instead of overwriting?

That multiplication is used by 3D formats imported from modeling tools, and enables various effects. material.color * vertex.color * texture.color allows any of those to modulate the others without requiring too many textures or meshes. If you want vertex colors to be the only colors used, set the material color to white.

@WestLangley Any chance you could answer this question:

I spent a couple minutes of my time writing this up and think that an overwrite might be a valuable feature.
