Our natural world offers endless interior design inspiration, from color palettes to sustainable decor options. In fact, Mark McCauley coined what’s known as the 3/3 vertical rule thanks to nature. According to the rule, it’s best to follow nature’s lead by displaying dark hues on the bottom, lighter tones in the middle, and the lightest hues on top—which mirrors nature.
A simple way to try this interior decor tip in your own apartment is to choose a dark-colored rug. For furniture that’s close to the ground, like coffee tables or ottomans, stick with darker shades.
Next, choose a medium hue for your couch, chairs, shelves, and other mid-level items. If you have white walls, you can choose to keep them that way or pick another light color to emulate the look of the outdoors.
