What color is Dulux Steel Symphony 4?

Dulux Steel Symphony 4 90BG 55/051 is a light, muted blue-grey with a clearly cool cast and a soft, low-saturation appearance. Its pale value keeps larger wall areas feeling open, while the grey content prevents the blue from reading overly crisp or bright. In north-facing rooms, Steel Symphony 4 may appear more distinctly blue and silvery; warmer daylight and artificial lighting can bring out its gentle grey side. It suits bathrooms, bedrooms, utility rooms, and contemporary living spaces, especially alongside white trim, pale oak, brushed nickel, and charcoal details. Use this color on full walls for an understated backdrop or on cabinetry where a subtle cool contrast is wanted.

LRV of Steel Symphony 4

Steel Symphony 4 has an LRV of 54% and refers to Light Medium colors that reflect half of the incident light. Why LRV is important?

Light Reflectance Value scale illustration

Light Reflectance Value measures the amount of visible and usable light that reflects from a painted surface.
Simply put, the higher the LRV of a paint color, the brighter the room you will get.
The scale goes from 0% (absolute black, absorbing all light) to 100% (pure white, reflecting all light).

Act like a pro: When choosing paint with an LRV of 54%, pay attention to your bulbs' brightness. Light brightness is measured in lumens. The lower the paint's LRV, the higher lumen level you need. Every square foot of room needs at least 40 lumens. That means for a 200 ft² living room you'll need about 8000 lumens of light – e.g., eight 1000 lm bulbs.
