Earl Blue vs Steel Symphony 4 in Real Spaces
2 real rooms side by side. Earl Blue and Steel Symphony 4 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Steel Symphony 4 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Steel Symphony 4 will make the room feel meaningfully brighter than Earl Blue would.
