What 27 tells you about Moody Blue
The published LRV of Sherwin-Williams Moody Blue SW-6221 is 27. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Moody Blue has greater depth than Stardew and carries green-gray undertones, making the green side a meaningful part of the blue choice.
The choice beside cream upholstery and walnut
Cream upholstery and walnut can restrain the surrounding palette, leaving the blue-green wall as the room's main color.
Draw the proposed dark area on a room photograph and compare it with a broad physical Moody Blue sample in shadow. The LRV describes the starting depth, while the size and location of that area determine its role. Check whether adjacent dark furniture remains legible.
What the comparison can—and cannot—settle
Moody Blue has an LRV of 27; Sherwin-Williams Stardew SW-9138 is 43. The difference is 16 points, with Stardew returning more light under the reference measurement. Moody Blue combines blue with green-gray undertones at a 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.
Compare it to a less green blue before choosing accessories; let the paint establish the direction. Do not read LRV 27 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.
