For an overdamped particle evolving in a potential and submitted to colored noise, we study numerically the problems of first passage time at the top of the potential and of stochastic resonance. In the limit where the correlation time of the noise is small compared to the other characteristic times of the problem we show that properties of the solution related to long time behavior are controlled by the zero-frequency component of the noise.
