We examined experimentally and theoretically polarization of THz radiation generated during dual-color (800nm+400nm) co-propagation of high-peak-power femtosecond laser pulses in gases. We reveal that THz radiation polarization is predominantly defined by the generation of the nonlinear photocurrent in the self - induced laser plasma and remains relatively stable with respect to the change of the initial polarization angle between the 800 nm and 400 nm light fields.
