  This article addresses persistent tangles. These are tangles whose presence
in a knot diagram forces that diagram to be knotted. We provide new methods for
constructing persistent tangles. Our techniques rely mainly on the existence of
non-trivial colorings for the tangles in question. Our main result in this
article is that any knot admitting a non-trivial coloring gives rise to
persistent tangles. Furthermore, we discuss when these persistent tangles are
non-trivial.
