Pewter Green vs Rock Garden in Real Spaces
6 real rooms side by side. Pewter Green and Rock Garden 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. Pewter Green 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. Pewter Green has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Pewter Green has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bathroom

Patio
Exterior colors look different in open light — both tend to read lighter outside than on an interior swatch, and shadows read more strongly. The brightness difference is modest but present — Pewter Green gives the walls a little more lift.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Pewter Green has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
