how to put different colors on different faces of a box

Haven’t tried it, but this might do it? https://threejs.org/docs/#api/en/textures/CubeTexture

i guess that could work id just have to use solid color images

you can use an array of materials, like this:

let box = new THREE.Mesh(
  boxGeometry,
  [
    new THREE.MeshStandardMaterial({ color: "red" }), // left
    new THREE.MeshStandardMaterial({ color: "green" }), // right
    new THREE.MeshStandardMaterial({ color: "blue" }), // top
    new THREE.MeshStandardMaterial({ color: "yellow" }), // bottom
    new THREE.MeshStandardMaterial({ color: "white" }), // front
    new THREE.MeshStandardMaterial({ color: "black" }) // back
  ]
);

You really want to use SDFT's solution if you can. It's a lot less wasteful.
