Stunning Sapphire vs Traffic blue
Stunning Sapphire (PPG) and Traffic blue (RAL Classic) come from different manufacturers. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 9 vs 11 — so neither will read significantly brighter or darker than the other. A ΔE of 2.5 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.

Digital color is approximate.
