S 0502-Y vs Functional Gray
S 0502-Y (NCS) and Functional Gray (Sherwin-Williams) come from different manufacturers. S 0502-Y reads as beige, while Functional Gray reads as greige-grey — two distinct hue families, not close cousins. The 50-point LRV gap — 87 for S 0502-Y vs 37 for Functional Gray — means S 0502-Y 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 27.4 puts these firmly in different territory — two distinct design choices rather than close alternatives.

S 0502-Y vs Functional Gray in Real Spaces
2 real rooms side by side. Seeing S 0502-Y and Functional 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. S 0502-Y reflects noticeably more light off the walls, making the space read more open than Functional Gray.
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. S 0502-Y returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

S 0502-Y vs Functional Gray Simulated Comparison
5 simulated room previews — drag the slider on each to see S 0502-Y on one side and Functional 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.
