Abstract
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.
