The hex value is the planner’s on-screen approximation, not a paint formula, and the light reflectance is estimated from it. Screens, daylight, bulbs and sheen all change how a paint looks, so check a physical sample or tester pot on your wall before you order. The official Farrow & Ball colour page has the manufacturer’s own details.
How Hague Blue behaves in a room
With an estimated light reflectance of about 7, it absorbs most of the light that reaches it. That makes a room feel enclosed and cosy, which is usually the point; plan lighting for the evening.
Its undertone is cool. In north-facing rooms, where daylight is cooler and bluer, cool colours can look colder and greyer than the swatch; in south-facing rooms they tend to look fresh and clean.
Where it tends to be used
Deep blues like this often go on dining room and study walls, kitchen islands and cabinets, front doors and bathroom walls.
