Firstly, you have to make the room more private. The more open it is to other people, the less romantic it will feel. When you're moving into a new place, make sure the most closed-off room is what you pick for your shared space. This means fewer and smaller windows, the door isn't that big, and it's a good distance away from all the other rooms. Make it feel like you’re in some remote resort in Koh Samui or something! However, if you can't control which room you get, close the outside world off with curtains. Beautiful chiffon ones will look great and can soften the room up a bit for maximum comfort appeal.
Speaking of a soft appeal, plush up your room with a lot of cushions and pillows. The bigger and cuddlier they are, the better! Incorporating a lot of softer elements in your room helps you relax better and easier. It gives you an idea that, wherever you are in the room, you'll still end up feeling cozy and comfortable. Even if you fall or trip, if there are enough pillows there, you can land on any one of them and you won't hurt yourself. And when you're you're at your most comfortable, you'll have an easier time getting into the mood.
As for the lighting, the dimmer, the better. Like you’re in a bar in Barcelona or something; it should be that dimly lit! That's why it's best to go for the lamps and lighting fixtures with which you can control the brightness. Because as much as you want your room to often feel romantic, at times, you'll need bright light to help you see stuff and look over your belongings. But during the times when you want to get into the mood, dim lighting helps a lot. It makes the room feel a lot more intimate as if you're the only two people in the world. Now, doesn't sound like the most romantic thing ever?
What about the scent of the room? What does a romantic room smell like? A rose scent, of course, is often a classic. But then again, you don't want your room to smell like a flower shop. Or worse, a Catholic church. Instead, go for more relaxing floral tones such as lilac and lavender. If you're able to better relax in your room, you'll easily get into a romantic mood. Vanilla can also work. It has its own sweetness, yes, but it's also light enough that your own natural smell can still linger on. Ultimately, your own personal scent is what your partner would prefer smelling.
Don't mistake intimacy for less space. There's giving off the illusion of a smaller and more intimate space, but at the end of the day, a smaller room is cause for claustrophobia. And you wouldn't want your partner getting scared to go into your room with you, would you? Of course not! So leave some extra legroom for you to walk around on. Provide ample areas where you can rest apart from your king or queen-sized bed. Just don't make your room too open as the feeling of intimacy won't be there anymore. Find the right balance and you'll be set!
This is perhaps the easiest to incorporate into your room. Just open up Spotify or Apple Music on your phone and you're good to go. Heck, even YouTube has its fair share of romantic playlists to get you into the mood. Now, if you think that music doesn't contribute to the whole vibe of a room, think again! While it's not exactly a permanent fixture, it makes all the difference. In fact, music can oftentimes dictate the mood of the room itself, no matter what it looks like inside. As long as you're playing the right tunes, the romance will blossom!
Finally, when it comes to colors, the warmer the better! Why do you think red is regarded as the most romantic color? The warmth it goes off evokes a fuzzy feeling inside. And more often than not, that funny feeling is love. So if you're planning to change the color of your room to something more romantic, red is the automatic option. However, it's not the only option. You can also go for other warm tones, like orange, violet, etc., but a bit more muted so as to not overwhelm your eyes. A neutral palette can also work to help you relax better!
A romantic room is not a difficult thing to achieve. You just have to know what gets you into the mood and work according to that! Though there are some universal design elements that can often help.
