based on reference, try find navigateuri

   public static hyperlink gethyberlink(this textpointer pointer)      {          if (pointer == null)          {              return null;          }                inline parent = pointer.parent inline;          while (parent != null && !(parent hyperlink))          {              parent = parent.parent inline;          }           return parent == null ? null : (hyperlink)parent;      }

using:

hyperlink hyperlink = richtextbox.selection.start.gethyberlink(); textrange textrange = new textrange(hyperlink.elementstart, hyperlink.elementend); textrange.applypropertyvalue(textelement.foregroundproperty, brushes.red);

result: navigateuri marked red.
