S 4010-G10Y vs Nephrite in Real Spaces
2 real rooms side by side. S 4010-G10Y and Nephrite 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. S 4010-G10Y has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
