Black and gold go well together because they contrast beautifully; black is deep darkness, while gold is the embodiment of sunlight. Due to this extreme difference between them, there is a great deal of space within that color pairing to find the exact palette to suit your own needs in each room, up to and including the bedroom. This goes for artwork as well, which is a vital part of any room's decor.
If you think of black and gold art in bold, modern terms, it may at first seem counterintuitive to plan on decorating a bedroom with such pieces. We go to the bedroom for rest, after all, and many people instinctively reflect that in their bedroom decor, choosing muted color palettes and indirect lighting. On the other hand, some people prefer a bolder tone in the bedroom, instinctively choosing art that will help wake them up in the mornings.
No matter which category you tend to fall under in choosing your bedroom art theme, consider the wide range of tones within the glamorous black and gold color pairing: Black is essentially neutral, and therefore goes harmoniously with anything else. Glamorous art also often softens black to shades of grey, from charcoal to mist, lending itself easily to a restful atmosphere in the bedroom. Gold, too, has its own spectrum, from bright sunshine-drenched sparkle to mellow, drowsy afternoon sunset, slanting through the trees in an old-growth forest. You can choose pieces in predominantly lighter lemony golds or deep autumnal shades that almost approach bronze; artwork is versatile, and can be adapted to any mood or theme you choose.
The artwork you choose for the bedroom can make the entire decorating scheme come together like magic. A piece where black predominates would catch the eye most effectively on a wall of contrasting color, and vice-versa. In the bedroom, the kind of artwork chosen will also be different from what you might choose for your kitchen or office, for instance; take note of the theme in each piece.
