Alloy vs Bedrock
Both are Sherwin-Williams colors. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. At LRV 34 vs 25, Bedrock will read as the brighter of the two — a 8-point gap that matters most in north-facing or low-light rooms. They share a neutral quality — useful to know if you're layering them in the same space. At ΔE 7.8, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 10 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Alloy vs Bedrock in Real Spaces
10 real rooms side by side. Alloy and Bedrock 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Bedrock returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that Bedrock will make the room feel meaningfully brighter than Alloy would.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The LRV gap is large enough that Bedrock will make the room feel meaningfully brighter than Alloy would.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. Bedrock reflects noticeably more light off the walls, making the space read more open than Alloy.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Bedrock will make the room feel meaningfully brighter than Alloy would.
Home Office
In a home office, wall color sits in your peripheral vision for hours at a time, so temperature and undertone matter more than you might expect. The LRV gap is large enough that Bedrock will make the room feel meaningfully brighter than Alloy would.
Mudroom
A mudroom color needs to hold up under the most casual scrutiny: a glance as you're coming and going, often in mixed or artificial light. Bedrock reflects noticeably more light off the walls, making the space read more open than Alloy.
Patio
Patio colors are seen under changing outdoor light throughout the day — morning, midday, and golden hour each reveal different qualities. Bedrock reflects noticeably more light off the walls, making the space read more open than Alloy.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The LRV gap is large enough that Bedrock will make the room feel meaningfully brighter than Alloy would.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Bedrock returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Alloy vs Bedrock Simulated Comparison
5 simulated room previews — drag the slider on each to see Alloy on one side and Bedrock on the other.
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.
