Treron vs Cloudy Slate
Treron (Farrow & Ball) and Cloudy Slate (PPG) come from different manufacturers. Hue-wise, Treron belongs to the greige-grey family and Cloudy Slate to the grey family. The 4-point LRV gap — 29 for Cloudy Slate vs 25 for Treron — means Cloudy Slate will open up a space more effectively. A ΔE of 10.3 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.
Treron vs Cloudy Slate in Real Spaces
8 real rooms side by side. Seeing Treron and Cloudy Slate 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. Cloudy Slate 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. Cloudy Slate has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Cloudy Slate 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 — Cloudy Slate 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. Cloudy Slate 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. Cloudy Slate 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. Cloudy Slate 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. Cloudy Slate reads slightly lighter here — a subtle but real difference in how open the space feels.

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