Cosmos vs Notable Hue
Cosmos and Notable Hue come from the same Sherwin-Williams collection. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Their light reflectance values are nearly the same — 38 vs 37 — so neither will read significantly brighter or darker than the other. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 3.0 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cosmos vs Notable Hue in Real Spaces
2 real rooms side by side. Cosmos and Notable Hue 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.
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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
