Hague Blue
Farrow & Ball
No. 30
Hague Blue is a deep, saturated navy with a noticeable green undertone, named for the strong blues the Dutch have long favored on their woodwork. It is one of Farrow & Ball's most-used colors for kitchen cabinetry, libraries, paneling, and front doors, and it holds up well fully drenched across walls and trim. Brass hardware, warm whites like Pointing, and aged wood tones all sit comfortably against it.

What is the Benjamin Moore equivalent of Hague Blue?

Is Hague Blue warm or cool?
Hague Blue is a cool color, though its green undertone keeps it from feeling icy. With an LRV of approximately 7, it absorbs far more light than it reflects, so it reads close to black in dim corners and reveals its blue-green depth in daylight. It tends to work best in rooms with generous natural light, or in small spaces where you lean into the darkness deliberately.
Why does Hague Blue look different on screen than on the wall?
Screens emit light while paint reflects it, so a hex code cannot capture how lighting, sheen, and surrounding colors shift paint in a real room. Treat #3F4D57 as accurate for digital design work, and use physical samples for final approval. Farrow & Ball does not publish official hex codes, so this value is a close third-party approximation.
What LRV does Hague Blue have?
Hague Blue has a Light Reflectance Value of approximately 7, meaning it reflects about 7% of visible light. That low value makes it a dramatic, light-absorbing choice that works well with strong natural light or as an accent.
