Give this sample a clear job
Sample Sherwin-Williams Charcoal Blue SW-2739 beside the fixed finishes, in the intended orientation and under normal room lighting. The trial should settle a nearly black blue for defined architectural areas . Charcoal Blue's low reflectance places it among the nearly black navy choices, not among light or medium blues.
Why the white shelves and warm oak relationship matters
White shelving can make the dark shape readable, while warm oak prevents the scheme from relying entirely on a blue-and-white contrast.
Charcoal Blue has an LRV of 6; Sherwin-Williams Sea Serpent SW-7615 is 7. The difference is 1 points, with Sea Serpent returning more light under the reference measurement.
Keep the comparison fair
Use a large dried Charcoal Blue 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
Decide whether black-like depth is welcome in the darkest corner; a navy name does not guarantee obvious blue everywhere. The undertones and neighboring colors covers that related choice. The trim color comparison covers that related choice.
Keep the approved dried board with the complete Sherwin-Williams SW-2739 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.
