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 Dulux colour page has the manufacturer’s own details.
How Rock Salt behaves in a room
With an estimated light reflectance of about 82, it bounces back most of the light that reaches it, so it helps small or dim rooms feel brighter and makes a good ceiling or trim colour.
It sits close to a true neutral, so it shifts less than most colours between cool northern light and warm southern light, though bulbs and nearby fabrics will still tint it.
Where it tends to be used
Whites like this are used on walls, ceilings and woodwork throughout a home, and on kitchen units. A white with this undertone keeps a scheme clean without feeling stark.
