Can't understand why mesh color is wrong

If you are using Three r155, then you need to increase the intensity of the ambient light.

scene.add(new THREE.AmbientLight(0xffffff, Math.PI));

“The intensities for ambient, hemisphere, directional lights and light maps can be restored by multiplying PI with the existing light intensity values” → Migrating

Also, this line does nothing when using the ambient light

@chungalunga

ambientLight.position.set(1, 1, 1).normalize();
