The correct choice is semi-permanent hair color, as it is specifically designed to temporarily change the hair's color without the long-lasting effects associated with permanent hair dye. Semi-permanent hair color contains a lower concentration of ammonia or may be ammonia-free, allowing it to deposit color onto the hair shaft without penetrating deeply. This means that it gradually washes out over several shampoos, making it an ideal option for someone looking to experiment with color or temporarily enhance their natural shade without a significant commitment.

In comparison to other products, permanent hair color provides a long-lasting change that cannot be easily reversed, as it penetrates the hair shaft completely and requires growing out or skillful removal by a stylist. Temporary rinses offer a very fleeting effect, often washing out after one or two washes, but they are generally less complex than semi-permanent colors and may not provide the same level of vibrancy. Highlighting kits are used to create contrasting strands or sections of color and are not intended for complete color changes, making them unsuitable for the purpose identified in the question.
