Choose by the material relationship as well as the number. Urbane Bronze offers brownish-gray depth where a stark black is not the desired relationship to stone. Porpoise is a gray-bronze color with deep reflectance.

The choice beside limestone cladding and bronze hardware
A metallic bronze sample changes with reflection; the paint can complement it without needing to reproduce the metal's highlights.
Set up both candidates with limestone cladding and bronze hardware. 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 Black Fox has an LRV of 7. The undertones and neighboring colors covers that related choice.
Compare actual metal finishes in shade; a painted brown-gray should complement the hardware rather than imitate its reflectivity. Assess Urbane Bronze and Porpoise 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.
