Having a bit of trouble with using GetComponentsInChildren.

private Material[] cachecolours;

void Start ()
    {
       //...

        cachecolours = transform.GetComponentsInChildren<Material>();
    }
void Update ()
    {
            foreach (Material colour in cachecolours)
            {
                colour.color = new Color(cs, cs, cs);
            }
    }

I want to change the colour of the materials of each child of my object but I keep getting these errors:

ArgumentException: GetComponent requires that the requested component ‘Material’ derives from MonoBehaviour or Component or is an interface.

and

NullReferenceException: Object reference not set to an instance of an object

I believe the second is due to the first but I can’t figure out how to change the colour of each child in turn.

cs is assigned a float value I just excluded that part of the code.

“In order to get the material used by an object, use the Renderer.material property.”
