What 17 tells you about Laguna Blue
The published LRV of Behr Laguna Blue PPU-14-18 is 17. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Laguna Blue is a deep oceanic color, so a coastal association should not create an expectation of pale, airy walls.
The choice beside pale oak and white linen
White linen and pale oak can provide contrast, while the dark blue carries the principal color in the room.
Draw the proposed dark area on a room photograph and compare it with a broad physical Laguna 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
Laguna Blue has an LRV of 17; Sherwin-Williams Smoky Blue SW-7604 is 15. The difference is 2 points, with Laguna Blue returning more light under the reference measurement. Laguna Blue is an oceanic blue with a deep reflectance value. 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.
Use it where a substantial blue surface is wanted, then check the evening corner before assuming an airy effect. Do not read LRV 17 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.
