If you love tropical hues but want to keep them a bit subdued, choose light shades of colors such as pink, green, yellow or blue. Paint your walls one or more of these colors. As you probably found on your vacation, these colors can go together in ways you hadn't considered yourself. Experiment with color combinations, such as soft pink and yellow. If you don't like it, you can always paint again. Complete your room with large, leafy plants and loosely-woven fabrics.
To recreate a beach-inspired tropical experience, choose wall colors inspired by sparkling turquoise waters and soft white sand. This is especially appropriate in spaces like bathrooms, and it's always easy to find lots of accessories, such as towels and seashell knickknacks. Paint your walls a tropical blue and your trim a soft sand. Alternatively, use the soft sand color in your flooring.
As Mother Nature does in the tropics, use hues that are opposite each other on the color wheel. This is a dramatic look. For example, choose a warm yellow orange for your walls and a deep bright blue for the trim. Alternatively, choose purple and green. Draw from the pair of colors when you decorate the rest of the room.
To keep the look of your room clean and fresh, start with a white palette. Paint the walls a clean, crisp white, and use your tropical colors as accents. If you find white walls too stark, tint the white to recreate the color of a tropical beach.
