Cornforth White vs Cool Slate
Cornforth White (Farrow & Ball) and Cool Slate (PPG) come from different manufacturers. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 60 vs 62 — so neither will read significantly brighter or darker than the other. A ΔE of 0.9 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cornforth White vs Cool Slate in Real Spaces
5 real rooms side by side. Cornforth White and Cool Slate 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
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. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

5 simulated room previews — drag the slider on each to see Cornforth White on one side and Cool Slate 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.
