The 14-point LRV gap — 64 for S 1502-Y vs 50 for Half Dome — means S 1502-Y will open up a space more effectively. ΔE 9.1 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
S 1502-Y vs Half Dome in Real Spaces
3 real rooms side by side. S 1502-Y and Half Dome 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. S 1502-Y reflects noticeably more light off the walls, making the space read more open than Half Dome.
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 S 1502-Y will make the room feel meaningfully brighter than Half Dome 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. S 1502-Y returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

S 1502-Y vs Half Dome Simulated Comparison
5 simulated room previews — drag the slider on each to see S 1502-Y on one side and Half Dome 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.
