What 77 tells you about Pearly White
The published LRV of Sherwin-Williams Pearly White SW-7009 is 77. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Pearly White's gray undertone makes it a different proposition from whites chosen primarily for yellow or beige warmth.
The choice beside cream cabinetry and gray-veined stone
A cream cabinet and gray-veined stone create two competing references; the paint must be judged against both together.
Read the narrow edge between Pearly White and the existing white from several steps away. Repeat with Natural Choice 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
Pearly White has an LRV of 77; Sherwin-Williams Natural Choice SW-7011 is 73. The difference is 4 points, with Pearly White returning more light under the reference measurement. Pearly White is a white with a cool gray undertone in the manufacturer's description. 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 both fixed finishes at once; a cool gray-white may connect them or make their difference clearer. Do not read LRV 77 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.
