Obsidian vs Agreeable Gray
Obsidian (PPG) and Agreeable Gray (Sherwin-Williams) come from different manufacturers. Hue-wise, Obsidian belongs to the blue-grey family and Agreeable Gray to the greige-grey family. The 52-point LRV gap — 60 for Agreeable Gray vs 8 for Obsidian — means Agreeable Gray will open up a space more effectively. A ΔE of 49.9 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 9 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Obsidian vs Agreeable Gray in Real Spaces
9 real rooms side by side. Seeing Obsidian and Agreeable 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. Agreeable Gray reflects noticeably more light off the walls, making the space read more open than Obsidian.
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. Agreeable 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. Agreeable 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 Agreeable Gray will make the room feel meaningfully brighter than Obsidian 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. Agreeable 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. Agreeable 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 Agreeable Gray will make the room feel meaningfully brighter than Obsidian 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. Agreeable 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. Agreeable Gray reflects noticeably more light off the walls, making the space read more open than Obsidian.

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