The decision for this particular color
Pewter Green can be considered for bathroom if its color and depth suit the space; the first design question is a green cabinet finish with deliberate depth. Pewter Green is already deep enough that shadow behavior is a central part of the cabinet decision.
Why the soapstone and brass hardware relationship matters
Soapstone beside deep green can reduce separation; brass handles add highlights but do not restore the missing boundary between large dark surfaces.
Pewter Green has an LRV of 12; Sherwin-Williams Rosemary SW-6187 is 14. The difference is 2 points, with Rosemary returning more light under the reference measurement.
Let tile and porcelain set the limits
Assess Pewter Green on the vanity or wall under the bathroom's actual lighting. Check the shadow below the countertop and the dark outline in the mirror. The porcelain can provide a large light contrast, but its brightness does not establish how the rest of the painted surface will read.
Separate the palette from the moisture specification
Check that the countertop and green cabinet remain distinguishable in the evening working light. The undertones and neighboring colors covers that related choice. The daylight and evening-light checks covers that related choice.
Choose a Sherwin-Williams coating appropriate to the bathroom surface and follow the manufacturer's preparation and application guidance. Color SW-6208 does not identify a moisture-control system. Ventilation, substrate condition and the intended finish are separate decisions; approve the color under the real vanity lighting before ordering the full paint quantity. The trim color comparison covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
