Superscattering has been proposed to enhance the total scattering cross-section significantly. Here we design three kinds of super-scatterers with maximum total scattering cross-sections at three primary colors. They are utilized to construct random systems, whose random lasing properties are analyzed. We find that the lasing thresholds are reduced by two orders of magnitude at these trichromatic wavelengths in respect to other wavelengths or compared to random systems with conventional scatterers.
