Make your pantry doors stand out with a coat of fresh white paint if you have dark walls or colored walls; the white paint will give your dark room a bright pop. You can also add a dark color to give contrast to a white kitchen -- this can be a bright pastel, a darker, elegant color or even a totally contrasting black. The advantage of working with paint is that it is inexpensive.
You can also wallpaper a set of pantry doors. A floral, paisley or stripe pattern adds instant style and character to your doors and, like paint, wallpaper is inexpensive. You can also update wallpaper easily as your taste changes. The downside of working with wallpaper is that it can rip or tear easily if it isn't high-quality; invest in better wallpaper if you want your pantry doors to look fresh for longer.
The molding and trim on your pantry doors also might use some improvement. Update the trim and molding for a fresh new look -- thicker molding and trim give off a more contemporary feel, while thinner versions offer a more casual look and style. You can also trim or frame a set of pantry doors with chrome for a retro look or brass for a modern twist.
Apply a pattern to your pantry doors -- consider an animal print, a polka dot print or a stripe. You can also use stencils and apply the alphabet, a family crest or an abstract print. The polka dot pattern is a whimsical idea that can work in a retro or more contemporary kitchen, while the stripe pattern is a more elegant or formal choice for the pantry doors.
