What is NOT a reason to use a contour color when applying eye color?

Using a contour color when applying eye color primarily serves purposes related to enhancing the appearance of the eyes through the creation of depth, definition, and drama. A contour color is typically a darker shade that helps to shape and define the eyes, contributing to the illusion of depth by creating shadows. This aspect is essential in eye makeup, as it can make the eyes appear more defined and help accentuate their natural shape.

The intention behind using contour color is also to create a dramatic look, which can be especially relevant for occasions where a more pronounced eye impact is desired. The contour color enhances features by highlighting the natural contours of the eye area, thus shaping the makeup application to be more visually interesting.

In contrast, evening out the skin tone on the eye area generally falls under the category of a foundation or concealer application rather than contouring. Contour colors are not meant for skin tone correction but instead for defining and enhancing the eye's features. Therefore, the use of contour color does not serve the purpose of achieving an even skin tone, making that particular choice not relevant when considering the functions of contour in eye makeup application.
