Choose one wall in your room to paint orange and serve as an accent wall. For instance, in a bedroom, you can choose the wall behind your bed to function as the accent wall.
Paint the other three walls a pale, neutral shade that looks good next to the color orange you have chosen. Be cautious with bright white because it could look stark next to the orange.
Decorate the room mostly in neutral shades with a pop of orange color here and there, such as in throw pillows, lampshades, rugs or artwork.
Choose a color combo that pairs well with orange, such as bright orange and royal blue, purple or red.
Decorate the room with different items that incorporate the colors you have chosen, such as an orange-and-royal-blue bedspread with a royal blue rug. Or do the same with a red and orange scheme.
Add a third color, such as yellow to a red-and-orange combo or a deep green to a blue-and-orange scheme. Incorporate the third color via artwork, towels, throw pillows or side tables.
