Basically Black vs Agreeable Gray
Basically Black (Dulux) and Agreeable Gray (Sherwin-Williams) come from different manufacturers. Hue-wise, Basically Black belongs to the blue-grey family and Agreeable Gray to the greige-grey family. The 51-point LRV gap — 60 for Agreeable Gray vs 9 for Basically Black — means Agreeable Gray will open up a space more effectively. Where Basically Black leans neutral, Agreeable Gray reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 50.2 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Basically Black vs Agreeable Gray in Real Spaces
5 real rooms side by side. Seeing Basically Black 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 Basically Black.
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.
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.
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 Basically Black.

Basically Black vs Agreeable Gray Simulated Comparison
5 simulated room previews — drag the slider on each to see Basically Black 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.
