What 41.9 tells you about Mount Saint Anne
The published LRV of Benjamin Moore Mount Saint Anne 1565 is 41.9. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Mount Saint Anne provides more blue-gray depth than Beach Glass, useful when pale cabinetry needs a stronger background.
The choice beside white cabinet doors and warm wood floors
White cabinet faces are a clear reference, but the warm floor determines whether the stronger blue-gray belongs in the whole room.
Compare Mount Saint Anne and Boothbay Gray at equal size, first considering depth and then hue. A lighter blue, green or pink is still a colored surface. Use the LRV to organize the depth question without assuming that it measures saturation or predicts which hue the room will favor.
What the comparison can—and cannot—settle
Mount Saint Anne has an LRV of 41.9; Benjamin Moore Boothbay Gray HC-165 is 43.26. The difference is 1.36 points, with Boothbay Gray returning more light under the reference measurement. Mount Saint Anne is a blue-gray with medium depth. 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.
Choose the extra wall depth for the cabinet contrast, with a separate evening check near the floor. Do not read LRV 41.9 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.
