The revised role of colored noises in the intracellular calcium oscillation (ICO) system are investigated by means of a first-order algorithm for the stochastic simulation of colored noises. The simulation results showed clearly that the colored noises commutate a calcium wave. Concretely, for a correlation time of colored noise τ1 there exists a threshold value τc which plays an important role in shifting a calcium wave from negative to positive, however, the calcium wave will show negative regardless of any noise's correlation time taking any value, so long as τ1 ＜ τc. So considering colored noises in the ICO could explain reasonably the ICO phenomenon.
