Match Your Style
When selecting a frame, choose one that either complements the style of the art or look to the decor of the room where it will be displayed.
The thickness of the frame can be one of the most important decisions in the selection process. Incorrectly sized framing will not enhance the art but distract from it. Although there are no absolute rules, these should help you through the selection process.
Matching your frame to a color in the art is not as important as matching the frame to your room decor. In fact, it's easy to overdo it when it comes to matching color. Keep in mind the overall color tone of the image, rather than specific colors. Warm tones (red, orange, brown) in the image would generally look better with warm frames such walnut and mahogany and with antique gold frames. Cool tones (blue, green, lavender) look better with light woods, natural woods and brighter gold frames.
It may not be possible to find an exact match for a frame you already own. An exact duplicate isn't necessary to create a harmonious set, and many designers avoid exact matches on principle. However, you should try to match the basic style and color. For example, a medium-width gold frame with a rope design will match a medium-width gold frame with a floral or beaded design. Matching color alone, and ignoring size, can be beautiful. For example, match a wide, glossy black frame with a medium-width glossy black frame. On the other hand, intentionally mismatching frames is a fundamental rule in eclectic decor style.
