I guess I was not clear in my original post. I am creating a background for a timer that also runs on the checkbox.
I want the background to ease into full color when the timer is running (clock runs when the checkbox is ON), but to ease out of color before the next keyframe (clock stops with checkbox is OFF). With the current code and the code you provided, the easing out of color occurs after the clock is stopped.
So I like that the first ease happens after the first keyframe but would like the second ease (easing out of color) to happen before the clock stops (second keyframe).
I guess my question is, is there even a way to code it such that the easing out of color happens before the second keyframe. Would it be simpler to hand-edit such a task? I was hoping to make it more automatic.
