Swansdown vs Glacier Bay
Where Swansdown belongs to Dulux's range, Glacier Bay is a Sherwin-Williams color. Both sit in the greige-white family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (76 vs 75), so they'll read as similarly Light in most lighting conditions. Swansdown runs warm while Glacier Bay is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. At ΔE 0.6, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Swansdown vs Glacier Bay in Real Spaces
3 real rooms side by side. Swansdown and Glacier Bay 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. The temperature contrast between Swansdown and Glacier Bay is what sets these apart most in this context.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Swansdown brings more warmth to the space, while Glacier Bay keeps things cooler and crisper.
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. Swansdown brings more warmth to the space, while Glacier Bay keeps things cooler and crisper.

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.
