What 73 tells you about Mountain Air
The published LRV of Sherwin-Williams Mountain Air SW-6224 is 73. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Mountain Air is a light green-blue pastel, so its airy description should not be mistaken for a warm neutral specification.
The choice beside honey wood and white cotton
Honey wood introduces warmth, but the sample on the shaded wall still needs to deliver a cool-color impression the room can support.
Compare Mountain Air and Misty 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
Mountain Air has an LRV of 73; Sherwin-Williams Misty SW-6232 is 64. The difference is 9 points, with Mountain Air returning more light under the reference measurement. Mountain Air is a light green-blue pastel. 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.
Check the shaded wall with the wood visible; an airy name cannot guarantee a warm-looking room. Do not read LRV 73 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.
