Gold may be the real color of money, but if you truly want to class up your place, you're going to have to retire your bling. Rooms filled with gilded items are, well, tacky. The color gets a lot of play in Donald Trump's pad and in rap videos, but that's not at all the look we're going for.
Instead of gold, use silver. Silver stands out without looking cheap or overdone. Chrome, brushed nickel or metallic grey are all colors that are sleek, classy and much easier on the eyes than gold. Multiple gilded frames are usually an eyesore, but a trio or small cluster of silver-plated pictures in different sizes is sophisticated.
