What 19.71 tells you about Cinnamon Slate
The published LRV of Benjamin Moore Cinnamon Slate 2113-40 is 19.71. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Cinnamon Slate's plum-brown mixture makes it a color choice with depth, rather than a generic neutral taupe.
The choice beside walnut furniture and neutral wool
Walnut can repeat the brown side while neutral wool leaves space for plum, avoiding a scheme in which every material adds mauve.
Draw the proposed dark area on a room photograph and compare it with a broad physical Cinnamon Slate 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
Cinnamon Slate has an LRV of 19.71; Benjamin Moore Velvet Plum CSP-420 is 12.45. The difference is 7.26 points, with Cinnamon Slate returning more light under the reference measurement. Cinnamon Slate blends plum and brown at a relatively deep 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.
Keep one large fabric deliberately neutral; let the plum-brown be the color statement. Do not read LRV 19.71 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.
