Steel Symphony 4 vs Parma Gray in Real Spaces
2 real rooms side by side. Steel Symphony 4 and Parma Gray are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Steel Symphony 4 reads slightly lighter here — a subtle but real difference in how open the space feels.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Steel Symphony 4 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
