  We review some difficulties of the standard picture of confining fields which
are viewed usually as `mild', or quasiclassical field configurations. The
paradoxes are naturally resolved by recent lattice observations of selftuned
fluctuations which exhibit both ultraviolet and infrared scales. The
ultraviolet scale is provided by the lattice spacing and is manifested in the
non-Abelian action density associated with the fluctuations while the physical
scale is exhibited by their geometrical characteristics. The data might suggest
existence of a dual description of Yang-Mills theories on the fundamental
level.
