Begin with the weaker light
Classic Gray can be assessed for a north-facing room, but the direction alone cannot determine the result. Its LRV is 73.67; the key concern is enough contrast to justify a second neutral . Classic Gray's lightness makes subtle separation its useful role; demanding a strongly outlined gray wall would suggest a different brief.
Why the white trim and pale limestone relationship matters
Pale limestone and white trim can leave little value contrast, so the decision may be about whether a second neutral is needed at all.
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.
Keep the surroundings in the test
For Classic Gray, build the observation around white trim and pale limestone. Place the board on the window wall and on a return wall facing another direction. Keep the material samples together as you move it. In a Northern Hemisphere north-facing room, daylight is often less directly sunlit, but trees, neighboring buildings, window size and the season can matter more than the compass label alone.
A lighting result needs a practical decision
Retain it for a gentle wall-to-trim difference, not a pronounced gray outline. The situations that call for another color covers that related choice.
Window size, obstruction and season still matter when choosing Classic Gray. A compass direction is not a brightness measurement. In the Northern Hemisphere, north-facing daylight is often less directly sunlit; the actual room remains the test. The daylight and evening-light checks covers that related choice.
