What 73.67 tells you about Classic Gray
The published LRV of Benjamin Moore Classic Gray OC-23 is 73.67. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Classic Gray's lightness makes subtle separation its useful role; demanding a strongly outlined gray wall would suggest a different brief.
The choice beside white trim and pale limestone
Pale limestone and white trim can leave little value contrast, so the decision may be about whether a second neutral is needed at all.
The editorial priority for this color is enough contrast to justify a second neutral. Place the Classic Gray board against the actual trim, then move it to the least illuminated part of the proposed wall. Judge the visible boundary from a normal viewing distance. A value that looks suitable on a table may produce too little distinction from one fixed finish and too much from another.
What the comparison can—and cannot—settle
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. Classic Gray sits near the off-white end of the gray range. 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.
Retain it for a gentle wall-to-trim difference, not a pronounced gray outline. Do not read LRV 73.67 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.
