What 51 tells you about Shiitake
The published LRV of Sherwin-Williams Shiitake SW-9173 is 51. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Shiitake's stony gray character within warmth makes stone the useful starting reference, rather than a generic beige furniture chip.
The choice beside sandstone and woven seating
Sandstone varies across a surface; an overall relationship is more credible than an exact match to one pale patch.
The editorial priority for this color is a stone-colored wall beside natural texture. Place the Shiitake board against the actual trim, then move it to the least illuminated part of the proposed wall. Judge the visible boundary from a normal viewing distance. A value that looks suitable on a table may produce too little distinction from one fixed finish and too much from another.
What the comparison can—and cannot—settle
Shiitake has an LRV of 51; Sherwin-Williams Accessible Beige SW-7036 is 58. The difference is 7 points, with Accessible Beige returning more light under the reference measurement. Shiitake is a warm neutral with a stony gray character. 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 a large stone sample with several tonal variations; one tiny beige fleck is not a sufficient match. Do not read LRV 51 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.
