Deepest Mauve vs Poetry Plum
Both from Sherwin-Williams's palette. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (11 vs 12), so they'll read as similarly Dark in most lighting conditions. Both lean warm, so they'll behave similarly in mixed or changing light conditions. At ΔE 1.8, 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 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Deepest Mauve vs Poetry Plum in Real Spaces
2 real rooms side by side. Deepest Mauve and Poetry Plum 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.
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.
