The decision for this particular color
Seapearl can be considered for bathroom if its color and depth suit the space; the first design question is a gray-white around warmer architectural materials. Seapearl's cool gray undertone separates it from whites selected mainly for creamy warmth.
Why the brick and pale limestone relationship matters
Brick and limestone create different colored boundaries, so a white that agrees with one still needs to be checked against the other.
Seapearl has an LRV of 76.43; Benjamin Moore Dove Wing OC-18 is 77.52. The difference is 1.09 points, with Dove Wing returning more light under the reference measurement.
Let tile and porcelain set the limits
Put Seapearl against the basin, tile background and grout simultaneously. A close white palette can expose small differences at every joint. Inspect under the vanity light and in the mirror, where reflections bring additional surfaces into the view before deciding which white should lead.
Separate the palette from the moisture specification
Test against both materials in the same light; a gray undertone can read differently next to each. 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-19 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.
