  The Nielsen - Olesen flux tube in the SU(2) Yang - Mills - Higgs theory
dressed with the color electric $E^a_{\rho,\phi}$ and magnetic
$H^a_{\rho,\phi}$ fields is derived. On the next step it is argued that this
flux tube can be considered as a result of the nonperturbatuve analytical
calculations in the SU(3) quantum theory.
