Cyberspace and Charcoal Blue: the documented difference
Cyberspace and Charcoal Blue both have a published LRV of 6. That equality describes reflectance, not matching colorants or identical undertones. Choose by the material relationship as well as the number. Cyberspace brings cool charcoal-black depth, so a nearly black wall is a reasonable possibility in weaker light. Charcoal Blue is a navy so deep that it approaches black.

| Charcoal Blue | Sherwin-Williams SW-2739 | 6 |
The choice beside cognac seating and white shelving
Cognac furniture and white shelving supply different kinds of contrast: warm color from one, a clear light outline from the other.
Set up both candidates with cognac seating and white shelving. Use equal-sized boards with the intended finishes and place them in the same orientation. Do not put one directly beside a window and leave the other in shadow. A difference that follows the position rather than the board is a lighting observation, not evidence that the formula changed.
What the comparison can—and cannot—settle
The alternative Sea Serpent has an LRV of 7.
Use the warmth of the furniture as contrast and check whether the shelving still defines the dark wall. Assess Cyberspace and Charcoal Blue alone as well as side by side. The unchosen board will not remain in the finished room, and a preference created only by that neighbor may not survive its removal. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
