Nail discoloration during manicure procedures is commonly associated with nail polish stains or fungal infections. When nail polish is applied, particularly dark colors or low-quality products, it can leave a stain on the nail bed if not properly removed or if the polish is left on for an extended period. This can lead to a yellowing or darkening of the nail surface.

Fungal infections also frequently lead to discoloration, often presenting as a yellow, green, or even black appearance. Fungi thrive in warm, moist environments, which can occur beneath the nail if there are gaps or improper hygiene during manicure processes. Regular sanitation and proper technique can help prevent these issues.

Improper filing techniques and the overuse of acrylics can damage the nail's surface and structure but do not typically cause discoloration directly. While using unsanitized tools poses serious risks for infections, it is the specific conditions associated with nail polish and fungal growth that most directly result in the visible discoloration of nails during manicures.
