The color the referenced transition's wire and arrow border is drawn with, or null when no line color override is applied.
This property sets the transition's wire and arrow border color only. Use TransitionReference.FillColor to set the transition arrow's fill color.
Setting null means no line color is applied, in which case the transition falls back to ITransition.LineColor.
Setting a new value overwrites any existing line color for that transition. Setting the value back to
null removes it.
Getting or setting this property has no effect, and getting it returns null, when the
TransitionReference has no associated TransitionReference.Context, such as when it is default.
Throws ObjectDisposedException when you access this property after you call Context.Dispose on the context.
TransitionReference transitionRef = context.GetTransitionReference(transitionID); transitionRef.LineColor = DebugStyles.Pending;
