Mount Saint Anne vs Wales Gray
Both from Benjamin Moore's palette. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. Wales Gray (LRV 54) reflects noticeably more light than Mount Saint Anne (LRV 42), a difference of 12 points that becomes especially apparent in rooms with limited natural light. Both lean green and blue, so they'll behave similarly in mixed or changing light conditions. The ΔE 7.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Mount Saint Anne vs Wales Gray in Real Spaces
6 real rooms side by side. Mount Saint Anne and Wales Gray 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 LRV gap is large enough that Wales Gray will make the room feel meaningfully brighter than Mount Saint Anne would.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Wales Gray reflects noticeably more light off the walls, making the space read more open than Mount Saint Anne.
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. Wales Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Wales Gray reflects noticeably more light off the walls, making the space read more open than Mount Saint Anne.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. Wales Gray reflects noticeably more light off the walls, making the space read more open than Mount Saint Anne.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Wales Gray reflects noticeably more light off the walls, making the space read more open than Mount Saint Anne.
