Soot vs Stiffkey Blue
Soot (Benjamin Moore) and Stiffkey Blue (Farrow & Ball) come from different manufacturers. Soot reads as blue-grey, while Stiffkey Blue reads as blue — two distinct hue families, not close cousins. The 4-point LRV gap — 10 for Stiffkey Blue vs 6 for Soot — means Stiffkey Blue will open up a space more effectively. Where Soot leans blue, Stiffkey Blue reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 14.6 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 8 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Soot vs Stiffkey Blue in Real Spaces
8 real rooms side by side. Seeing Soot and Stiffkey Blue in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Stiffkey Blue reads slightly lighter here — a subtle but real difference in how open the space feels.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Stiffkey Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The brightness difference is modest but present — Stiffkey Blue gives the walls a little more lift.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Stiffkey Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. Stiffkey Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Stiffkey Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Stiffkey Blue reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Stiffkey Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Soot vs Stiffkey Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Soot on one side and Stiffkey Blue 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.
