What is the primary purpose of wood stain?

The primary purpose of wood stain is to enhance and change the color of the wood. Wood stains are formulated to seep into the fibers of the wood, allowing the natural grain and texture to show through while adding pigment. This process allows for a wide variety of aesthetic choices, giving wood different appearances that can complement various design schemes and environments. By adjusting the color, stains can enrich the visual appeal of the wood, highlight its features, and create a more finished look, making it a popular choice in woodworking and cabinetry.

While some finishes might offer added benefits such as protection against insects or an increase in shine, these elements are secondary to stain's main function, which is focused on color enhancement.
