What 76.43 tells you about Seapearl
The published LRV of Benjamin Moore Seapearl OC-19 is 76.43. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Seapearl's cool gray undertone separates it from whites selected mainly for creamy warmth.
The choice beside brick and pale limestone
Brick and limestone create different colored boundaries, so a white that agrees with one still needs to be checked against the other.
Read the narrow edge between Seapearl and the existing white from several steps away. Repeat with Dove Wing in that same position. The question is whether the wall needs a barely visible transition or an obvious boundary; a high LRV can support either result depending on its neighbor.
What the comparison can—and cannot—settle
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. Seapearl is a white with cool gray undertones. The value measures reflectance, so it cannot by itself identify an undertone, a coating finish or the amount of illumination needed in the room. The daylight and evening-light checks covers that related choice.
Test against both materials in the same light; a gray undertone can read differently next to each. Do not read LRV 76.43 as a percentage improvement in perceived room brightness. Make the decision with the board upright at the actual wall or cabinet position, including the least illuminated portion. The north-facing room assessment covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
