Heron Plume vs Sanctuary
Both from Sherwin-Williams's palette. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. They have nearly identical light reflectance values (75 vs 76), so they'll read as similarly Light in most lighting conditions. Both lean warm, so they'll behave similarly in mixed or changing light conditions. At ΔE 0.4, 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.
Heron Plume vs Sanctuary in Real Spaces
3 real rooms side by side. Heron Plume and Sanctuary 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 two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
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. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

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.
