Why can't I change the texture: tint colour, with legacy animations?

I've been trying to change the tint colour with a legacy animation type,


and when I try to play it with Animation; it doesn't update the colour tint.




But when I don't use the legacy animation type,

and when I try to play it with Animator; it updates the colour tint.

Does anyone know why this is? And is it fixable?

~ I can't use Animator as it constantly loops the clips irrespective of when their called, and consequently my animations are occurring at the wrong times. .
