An accessory can appear more significant by using contrasting colors around it and lighting it with an accent light. Elaborate artwork or frames typically look better on plain painted walls than on patterned wallcovering which may compete with it. If you want the artwork to stand out, hang it on a contrasting colored wall, or light the art with a framing projector, or picture light that clamps onto the frame.
Mirrors are an easy and beautiful way to add light and space to a room.
In a small dark room, add mirrors along a wall opposite a window to reflect more light into the room. Mirrors generally cast a cool frosty reflection, but in a room with warm colors, they take on a warmer tone, reflecting the colors in the room. Locating a large mirror over the mantel on your fireplace will help make your fireplace a focal point by creating light and attracting the eye.
