Renderer material simple question

I have a simple question ... with this line: renderer.material.color = Color.Red change de color of material ... but how i can back to the original material color later?

(i apply this on a object texture)


Save it somewhere

var originalColor : Color = renderer.material.color;

renderer.material.color = Color.Red

// Waits 5 seconds
yield WaitForSeconds (5);

renderer.material.color = originalColor;
