Give this sample a clear job
Sample Sherwin-Williams Black Magic SW-6991 beside the fixed finishes, in the intended orientation and under normal room lighting. The trial should settle a warm black comparison at equal reflectance . Black Magic and Tricorn Black share the same LRV, so a claimed brightness advantage would be unsupported.
Why the warm white plaster and brass relationship matters
Warm plaster and brass provide a reason to compare Black Magic's slight warmth, using authentic samples rather than the numerical tie alone.
Black Magic and Tricorn Black both have a published LRV of 3. That equality describes reflectance, not matching colorants or identical undertones.
Keep the comparison fair
Use a large dried Black Magic board and inspect it at the darkest intended position. Photograph the area only as a planning record; judge the color in person with the normal lamps. Compare the full painted shape before assuming a small dark chip predicts the room's enclosure.
Approve the actual coating and the least favorable view
Test it directly against Tricorn Black; equal LRV does not mean an identical color impression. The trim color comparison covers that related choice.
Keep the approved dried board with the complete Sherwin-Williams SW-6991 product and finish specification. Follow the actual coating instructions for application, drying and preparation; the color name does not settle those requirements. The daylight and evening-light checks covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
