Colorelectric and Colormagnetic structure of the flux tubes, connecting heavyquark and antiquark, is investigated in the framework of the Field Correlatormethod which describes all resulting fields in terms of correlators $D^E$ and$D^E_1$. The latter have been computed via gluelumps, which allows to predictthe resulting distribution of color fields $\mathbf{E} (\mathbf{r}),$ andcolormagnetic currents $\mathbf{k} (\mathbf{r})$ in the flux tubes. It isshown, that at large distances $r\gg \lambda \approx 0.2$ fm the wholestructure of fields and relations between them is similar to that of the dualsuperconductor theory, but the basic dynamics, including small distances, isgiven by field correlators of the real stochastic vacuum. The importantcontradiction between the strong screening of color fields in the width of fluxtubes and almost no screening in the perturbative $Q\bar Q$ potential isresolved.
