|Stroke Color overrides the color of a stroke set in Border & Shadow, allowing it to be animated over time.
Stroke Color is used to animate the color of a stroke, which is not possible directly in Border & Shadow. It has one parameter: Color.
Color changes the color of the stroke of a layer. When using keyframe animation, color on each individual frame between keyframes will be a proportional mix of each keyframe color, creating a smooth transition between keyframe colors over time.
Note that Stroke must be enabled in Border & Shadow to see the effects of Stroke Color.
