The floor finish is the reference
Judge Velvet Plum against your actual wood finish, not a generic wood species label. The starting material direction here is walnut and cream wool. Velvet Plum is deeper than Cinnamon Slate and offers a smoky purple direction rather than the same plum-brown balance.
Walnut can lose definition against a dark plum wall, so cream wool may need to occupy a meaningful area of the room.
Test the dominant wood color, not one grain line
Check the outline between Velvet Plum and the darkest part of the floor or wood furniture. Deep paint and dark timber may lose separation in evening light. Decide whether that continuous dark effect is intended, or whether a lighter painted boundary would give the room clearer structure.
Velvet Plum has an LRV of 12.45; Benjamin Moore Cinnamon Slate 2113-40 is 19.71. The difference is 7.26 points, with Cinnamon Slate returning more light under the reference measurement.
The condition for keeping Velvet Plum
Reserve enough pale fabric to distinguish the plum walls from the wood, especially under evening lamps. The undertones and neighboring colors covers that related choice. The trim color comparison covers that related choice.
Keep the Velvet Plum board vertical at the floor edge. A match to one pale grain line can misrepresent the dominant color across the installed floor. Judge the broad timber background from standing height. If the floor will be refinished, repeat the comparison with the approved new stain sample before ordering the wall paint. The coordinating color options covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
