What 68 tells you about Olympus White
The published LRV of Sherwin-Williams Olympus White SW-6253 is 68. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Olympus White's blue-gray undertone makes it an intentional cool-white choice rather than a neutral match to all ceramic whites.
The choice beside white tile and silver metal
Silver metal can repeat the cool direction, but the tile edge is the larger permanent relationship to approve first.
Read the narrow edge between Olympus White and the existing white from several steps away. Repeat with Misty 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
Olympus White has an LRV of 68; Sherwin-Williams Misty SW-6232 is 64. The difference is 4 points, with Olympus White returning more light under the reference measurement. Olympus White is a white with a blue-gray undertone. 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.
Compare the tile edge in daylight before treating the blue-gray as a neutral bathroom backdrop. Do not read LRV 68 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.
