S 1002-Y vs Grey Mist
S 1002-Y (NCS) and Grey Mist (Sherwin-Williams) come from different manufacturers. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. The 3-point LRV gap — 75 for Grey Mist vs 72 for S 1002-Y — means Grey Mist will open up a space more effectively. Both share a warm character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 1.7 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
S 1002-Y vs Grey Mist in Real Spaces
4 real rooms side by side. S 1002-Y and Grey Mist are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
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. Grey Mist reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Grey Mist 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 — Grey Mist gives the walls a little more lift.
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. Grey Mist has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

S 1002-Y vs Grey Mist Simulated Comparison
5 simulated room previews — drag the slider on each to see S 1002-Y on one side and Grey Mist 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.
