A hair color brush is specifically designed for applying hair color and allows for precise and even distribution of color. Its bristles can vary in stiffness and density, helping to ensure that the color is applied uniformly onto the hair strands. This tool is particularly useful for various coloring techniques, such as highlights or balayage, where control over application is important. Additionally, the shape and design of a hair color brush facilitate reaching different sections of the hair, making it an essential tool for professionals in the field of cosmetology.

The other options, while they may seem applicable, are not as widely recognized or effective for hair color application. For example, a hair color sponge may absorb too much product and can lead to uneven application, while a hair color comb can be useful for distribution but lacks the precision of using a brush. A hair color roller might be used in some techniques but is not as standard in color application as the brush. Thus, the hair color brush is the appropriate choice for this task.
