  We present a universal knot polynomials for 2- and 3-strand torus knots in
adjoint representation, by universalization of appropriate Rosso-Jones formula.
According to universality, these polynomials coincide with adjoined colored
HOMFLY and Kauffman polynomials at SL and SO/Sp lines on Vogel's plane, and
give their exceptional group's counterparts on exceptional line. We demonstrate
that [m,n]=[n,m] topological invariance, when applicable, take place on the
entire Vogel's plane. We also suggest the universal form of invariant of figure
eight knot in adjoint representation, and suggest existence of such
universalization for any knot in adjoint and its descendant representation.
Properties of universal polynomials and applications of these results are
discussed.
