Night Jewels 3 vs Slate Mine in Real Spaces
2 real rooms side by side. Night Jewels 3 and Slate Mine 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. Night Jewels 3 reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Night Jewels 3 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
