I want a tween which allows the colour to fade from one to another over the course of the tween
this did not work when i applied a motion tween
so which type of tween do i need
What are you trying to change the color of... what type of object?
i just want to change an objects colour, over the course of a series of frames,
You'll need to describe the details of what you tried that did not work, step by step.
