An approach is proposed for producing a multi-colored noise from rednoise to green one, and the correlation and spectral functions of this noise are given.
阐述了一个产生从红噪声到绿噪声的多色噪声源的途径，给出了这种噪声的关联函数和谱密度。

The results show that the direction of the current driven by the green noise is opposite to the one driven by the rednoise, and there is a noise with certain color which makes the current reversal.
