three.js - Superimposing of color -

i want paint cubes red color means of mouse. green cube (at left) becomes not red, black. white cube (on right) colored normally. do? example here

// init var material = new three.meshlambertmaterial({     color: 0x00ff00,     side: three.doubleside,     vertexcolors: three.facecolors });  var geometry = new three.boxgeometry(100, 100, 100, 4, 4, 4);  var cube = new three.mesh(geometry, material); cube.position.x = -100; scene.add(cube); objects.push(cube);  var material = new three.meshlambertmaterial({     color: 0xffffff,     side: three.doubleside,     vertexcolors: three.facecolors }); var geometry = new three.boxgeometry(100, 100, 100, 4, 4, 4);  var cube = new three.mesh(geometry, material); cube.position.x = 100; scene.add(cube); objects.push(cube);  document.addeventlistener('mousedown', ondocumentmousedown, false);  //   function ondocumentmousedown(event) {      var vector = new three.vector3(         (event.clientx / window.innerwidth) * 2 - 1, -(event.clienty / window.innerheight) * 2 + 1, 0.5);     vector.unproject(camera);     raycaster.set(camera.position, vector.sub(camera.position).normalize());       var intersects = raycaster.intersectobjects(objects);      if (intersects.length > 0) {         var index = intersects[0].faceindex;         // change color of closest face.         intersects[0].face.color = color;         intersects[0].object.geometry.colorsneedupdate = true;     }  }

scrin

in example, final color component-wise product of material color ( 0x00ff00 ) , face color ( 0xff0000 ), results in black ( 0x000000 ).

for reason, when have face colors, idea set material color white.
