The decision for this particular color

Classic Gray can be considered for bathroom if its color and depth suit the space; the first design question is enough contrast to justify a second neutral. Classic Gray's lightness makes subtle separation its useful role; demanding a strongly outlined gray wall would suggest a different brief.

Why the white trim and pale limestone relationship matters

Pale limestone and white trim can leave little value contrast, so the decision may be about whether a second neutral is needed at all.

Classic Gray has an LRV of 73.67; Benjamin Moore Pale Oak OC-20 is 68.64. The difference is 5.03 points, with Classic Gray returning more light under the reference measurement.

Let tile and porcelain set the limits

Put the Classic Gray sample next to the basin, the largest tile and the grout line. Turn on the vanity light and view the sample directly, then in the mirror; reflections can add other colored surfaces to the scene. The white trim and pale limestone direction is a starting idea, but the bathroom's actual ceramic and stone take priority over an inspiration palette.

Separate the palette from the moisture specification

Retain it for a gentle wall-to-trim difference, not a pronounced gray outline. The undertones and neighboring colors covers that related choice. The daylight and evening-light checks covers that related choice.

Choose a Benjamin Moore coating appropriate to the bathroom surface and follow the manufacturer's preparation and application guidance. Color OC-23 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. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
