The choice beside black metal windows and cream plaster
A black window frame may sit close to the paint in value, making a deliberate distinction more important than a supposed exact dark match.
Set up both candidates with black metal windows and cream plaster. Use equal-sized boards with the intended finishes and place them in the same orientation. Do not put one directly beside a window and leave the other in shadow. A difference that follows the position rather than the board is a lighting observation, not evidence that the formula changed.
What the comparison can—and cannot—settle
The alternative Peppercorn has an LRV of 10. The undertones and neighboring colors covers that related choice.
Compare the charcoal with the window finish so a close-but-different dark edge looks intentional. Assess Grizzle Gray and Rock Bottom alone as well as side by side. The unchosen board will not remain in the finished room, and a preference created only by that neighbor may not survive its removal. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
