Steel Symphony 4 vs Gray Frost
Steel Symphony 4 (Dulux) and Gray Frost (PPG) come from different manufacturers. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Their light reflectance values are nearly the same — 54 vs 52 — so neither will read significantly brighter or darker than the other. A ΔE of 2.3 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.
