What 49 tells you about Rain
The published LRV of Sherwin-Williams Rain SW-6219 is 49. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Rain is a cool green-gray whose weather name does not establish how blue the finished room will appear.
The choice beside white linen and weathered oak
White linen and weathered oak create a restrained setting in which a bluer control can clarify the desired color direction.
Compare Rain and Coastal Plain 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
Rain has an LRV of 49; Sherwin-Williams Coastal Plain SW-6192 is 37. The difference is 12 points, with Rain returning more light under the reference measurement. Rain is a cool green-gray with a moderate 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.
Compare a bluer candidate alongside it; decide which direction suits the existing fabric. Do not read LRV 49 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.
