Cloudy Slate vs Pittsburgh Gray
Cloudy Slate and Pittsburgh Gray come from the same PPG collection. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. The 30-point LRV gap — 59 for Pittsburgh Gray vs 29 for Cloudy Slate — means Pittsburgh Gray will open up a space more effectively. A ΔE of 20.9 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 10 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cloudy Slate vs Pittsburgh Gray in Real Spaces
10 real rooms side by side. Seeing Cloudy Slate and Pittsburgh Gray 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. Pittsburgh Gray reflects noticeably more light off the walls, making the space read more open than Cloudy Slate.
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. Pittsburgh Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Pittsburgh Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Pittsburgh Gray will make the room feel meaningfully brighter than Cloudy Slate would.
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. Pittsburgh Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Pittsburgh Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. The LRV gap is large enough that Pittsburgh Gray will make the room feel meaningfully brighter than Cloudy Slate would.
Patio
Exterior colors look different in open light — both tend to read lighter outside than on an interior swatch, and shadows read more strongly. The LRV gap is large enough that Pittsburgh Gray will make the room feel meaningfully brighter than Cloudy Slate would.
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. Pittsburgh Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Pittsburgh Gray reflects noticeably more light off the walls, making the space read more open than Cloudy Slate.

Cloudy Slate vs Pittsburgh Gray Simulated Comparison
5 simulated room previews — drag the slider on each to see Cloudy Slate on one side and Pittsburgh Gray 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.
