Steel Symphony 4 vs Daydream
Where Steel Symphony 4 belongs to Dulux's range, Daydream is a Sherwin-Williams color. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. They have nearly identical light reflectance values (54 vs 54), so they'll read as similarly Medium in most lighting conditions. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 3.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Steel Symphony 4 vs Daydream in Real Spaces
2 real rooms side by side. Steel Symphony 4 and Daydream 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. The distinction reads clearly at room scale, making the choice between them concrete.
