A toner is primarily used in hair coloring to adjust and refine the tone of the hair after it has been bleached. When hair is lightened, it often takes on undertones that may not be desirable, such as brassy yellows or oranges. Toners contain pigments that can neutralize these undertones, allowing for a more flattering and balanced color.

For example, if the hair appears too yellow after bleaching, a purple toner can be used to counteract that yellow, resulting in a more neutral or even cool blonde. This process is important in achieving the desired final shade and ensuring a harmonious look. Toners can also enhance existing color tones, making them richer and more vibrant.

In contrast, the other options do not accurately describe the function of a toner. While lightening the hair color, removing hair dye, or providing a temporary color may relate to other products or processes in hair coloring, they do not capture the specific role that toners play in refining color post-bleaching.
