Changing color of cube in three.js

Question

I\'m trying to change the color of a cube based on a variable. I created two cubes and I want to change their color depending on the distance between them.

The cubes

Answer 1

cube.material.color 

will give you the THREE.Color object:

Color

which has a bunch of methods you can use to set the color.

Answer 2

You are not specifying the color value correctly.

cube.material.color.setHex( 0xffffff );

Answer 3

My suggestion is attach a function to your object and then you can change the color of object during runtime easily.
Based on your code

geometry = new THREE.CubeGeometry( 50, 50, 50 );
material = new THREE.MeshBasicMaterial( { color: 0xff0000, wireframe: true } );
cube = new THREE.Mesh( geometry, material );

//here is the funcion defined and attached to the  object
cube.setColor = function(color){
     cube.material.color.set(color);
}


cube.setColor(0xFFFFFF)  //change color using hex value or
cube.setColor("blue")    //set material color by using color name

scene.add( cube );
