It’s hard to miss the Hotel Pantone. Located in the center of Brussels, Belgium, the clean, white 1970’s building easily draws the eye in with rectangular bricks of color from windows and room terraces, a subtle nod to the vivid Pantone rainbow that lies inside.

The Hotel Pantone opened its doors in 2010, but a recent push for bookings is making the color-coded rooms look brighter than ever. “Pantone is right at home in the heart of this vibrant city center, having long been synonymous with color and design in all walks of life, from high fashion and interior design to corporate branding,” says Lisa Herbert, Pantone executive vice president.

Architect Olivier Hannaert (who’s also responsible for Brussels’ Vintage Hotel) designed the modern seven-story building, which is situated just off chic Avenue Louise, home to shops like Louis Vuitton, Hermès, and Christian Dior. But the concept for the interior was the work of Belgian interior designer Michel Penneman. Each floor is assigned a specific color palette (created by utilizing Pantone’s famous color matching system) designed to allow guests to “transform their travels by selecting a room that complements their mood through color.”

Each of the 59 rooms are denoted by Pantone swatches (who hasn’t wanted to be surrounded by 520 C?), but the walls and bedding are kept stark white to offset the (sometimes very intense) use of color in hallways, common rooms, and the matchy-matchy in-room photography, custom created to match the hue of each room by Belgian photographer Victor Levy–to say nothing of the coordinated toilet paper and other bathroom amenities.

Guests who venture outside the rooms are treated to Pantone bicycles, those famous coffee mugs (natch), and a rooftop bar (where you can order a drink named for its color) and terrace that overlooks the city. If the surroundings have piqued your creativity, you can freshen up on your color theory in the corner library or book an appointment with a Pantone Color consultant to talk about color trends and psychology, like how your room’s 15-5519 is affecting your mood that day.

If you’re worried your post-Pantone life will look a little drab, they’ve taken care of that too—stop by the gift shop on your way out to stock up on Pantone products, from iPhone covers to cuff links, that you can take back home. And if just talking about all this color is making you reach for your shades, might we make a suggestion to the folks at Pantone for a 425 U floor? (For those who don’t speak Pantone, that would be grey.)
