What 9 tells you about Roycroft Bronze Green
The published LRV of Sherwin-Williams Roycroft Bronze Green SW-2846 is 9. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Roycroft Bronze Green has enough depth to act as a dark architectural color, irrespective of the historic association in its name.
The choice beside red brick and copper-colored metal
Red brick and copper-colored metal are specific warm neighbors; a heritage name cannot guarantee compatibility with their exact finishes.
Draw the proposed dark area on a room photograph and compare it with a broad physical Roycroft Bronze Green 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
Roycroft Bronze Green has an LRV of 9; Benjamin Moore Cypress Green 509 is 35.09. The difference is 26.09 points, with Cypress Green returning more light under the reference measurement. Roycroft Bronze Green is a deep green with a low 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.
Test the actual brick and metal together before treating the historic name as a guaranteed period match. Do not read LRV 9 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.
