The purpose of using a primer in nail applications is to promote adhesion. Primers are specially formulated products designed to increase the bond between the natural nail and the artificial products, such as acrylic or gel. By creating a slightly roughened surface on the nail, primers help the artificial materials adhere better, which reduces the chances of lifting or peeling and extends the longevity of the nail enhancement.

In contrast, the other options do not accurately describe the primary role of a primer. While hydration may be necessary for overall nail health, it is not the function of a primer. Enhancing color could involve the use of polish or pigments rather than primer. Additionally, primers may help prevent staining indirectly by ensuring that the application bonds well and does not allow products to seep through and stain the natural nail, but preventing staining is not their primary purpose.
