I see no clear way of defining the material at your sample code, or at least the way three.js does it:
var material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
If you use as a material a texture with an image, you have many ways to change its color... one easy trick could be to change the light color that lightens the scene or this object.
