We investigate the influence of a constant uniform external chromomagnetic field H on the formation of color superconductivity. The consideration is made in the framework of a (2+1)-dimensional Nambu{endash}Jona-Lasinio model with two different four-fermionic structures responsible for {l_angle}{bar q}q{r_angle} and diquark {l_angle}qq{r_angle} condensates. In particular, it is shown that there exists a critical value H{sub c} of the external chromomagnetic field such that at H{gt}H{sub c} a nonvanishing diquark condensate is dynamically created (the so-called chromomagnetic catalysis effect of color superconductivity). Moreover, external chromomagnetic fields may in some cases enhance the diquark condensate of color superconductivity.
