ColorTween class Null safety

An interpolation between two colors.

This class specializes the interpolation of Tween<Color> to use Color.lerp.

The values can be null, representing no color (which is distinct to transparent black, as represented by Colors.transparent).

See Tween for a discussion on how to use interpolation objects.
