According to the uniform coloring agent adding method for the overflow dyeing machine, a means of controlling the opening and closing time and frequency of a fine (coarse or simultaneous) feeding valve is realized, so that the design purpose that the coloring agent is uniformly added into the dyeing liquid, and the color concentration of the dyeing liquid meets the process requirement is achieved; therefore, the quality requirements on the coloring uniformity and stability of the fabric are met. A coloring agent atomizing and adding device is arranged at the vertical middle upper part of the dye vat and below the vertical side of the atomizing nozzle, and the coloring agent is sprayed downwards from the atomizing nozzle in a vaporific manner; the coloring agent is uniformly sprayed on the dye liquor at the bottom of the dye vat under the action of gravity, the coloring agent and the dye liquor are fully mixed through stirring, and the concentration of the dye liquor in the dye vat is kept consistent; the addi
