In this work, we study systematically the mass splittings of the (
, d, s and
, b) tetraquark states with the color-magnetic interaction by considering color mixing effects and estimate roughly their masses. We find that the color mixing effect is relatively important for the
states and possible stable tetraquarks exist in the
(
, d) and
systems either with
or with
. Possible decay patterns of the tetraquarks are briefly discussed.
