Granite Boulder vs Patchwork Plum in Real Spaces
2 real rooms side by side. Granite Boulder and Patchwork Plum 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. The distinction reads clearly at room scale, making the choice between them concrete.
