Acier vs Extra White
Acier and Extra White come from the same Sherwin-Williams collection. Hue-wise, Acier belongs to the grey family and Extra White to the white family. The 54-point LRV gap — 86 for Extra White vs 32 for Acier — means Extra White will open up a space more effectively. Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 31.0 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Acier vs Extra White in Real Spaces
3 real rooms side by side. Seeing Acier and Extra White 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. Extra White reflects noticeably more light off the walls, making the space read more open than Acier.
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. Extra White returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Extra White returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Acier vs Extra White Simulated Comparison
5 simulated room previews — drag the slider on each to see Acier on one side and Extra White 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.
