Deep Space
What Deep Space Actually Looks Like
Deep Space is a very dark charcoal gray that sits close to the boundary between gray and near-black. It reads as a true dark neutral in most rooms, with a cool, slightly blue-gray quality that keeps it from feeling muddy or warm. In bright light it shows its gray character clearly. In low or dim light it can read almost black.
Deep Space Undertones
The hex and RGB values place this color in cool territory, with blue and gray working together rather than any green or brown pull. There is no meaningful warm undertone here. On north-facing walls or in rooms with limited natural light, that cool character becomes more pronounced.
Where Deep Space Works Best
Deep Space works well as a full-room color in spaces where you want drama and enclosure, such as a home office, dining room, or library. It is also a strong choice for a single accent wall, exterior shutters and doors, or cabinetry where you want depth without going fully black. Because its LRV is very low, it absorbs light aggressively, so it suits rooms where intimacy is the goal more than rooms that need to feel open and bright.
Where to put Deep Space
A very dark wall color like Deep Space creates a focused, cave-like feeling that many people find helps with concentration. Keep the desk surface and shelving light to maintain enough contrast to work comfortably.
Deep Space at dinner-party scale, with candlelight or warm-toned pendant fixtures, creates a cozy and enveloping atmosphere. Pair with a light ceiling so the room does not feel like a closed box.
This color reads as a sophisticated dark charcoal from the street, a step softer than flat black but still bold. It complements both warm brick and light painted siding.
On kitchen or bathroom cabinetry, Deep Space delivers strong visual weight without the harshness of true black. Use a semi-gloss or satin finish to let the color show some depth and make cleaning practical.

Benjamin Moore Deep Space has the color code 2125-20. Its precise LRV is 10.8, which places it firmly in the very dark range. Hex and RGB values are shown in the color spec block on this page.
It depends on your light. In a well-lit room with natural daylight, it reads as a dark charcoal gray with a cool blue-gray quality. In low light or at night under incandescent bulbs, it can shift toward near-black. It rarely reads as a medium gray.
Eggshell is a solid everyday choice for walls because it is easy to clean and does not draw attention to imperfections the way flat finishes can. Matte works if you want maximum depth and no sheen. Satin or semi-gloss makes sense for trim, doors, and cabinetry.
Yes, particularly for doors, shutters, and exterior trim details. It reads as a refined dark charcoal from a distance and holds up well against a range of siding colors. For full exterior body use, confirm your local building codes and HOA rules allow a color this dark.
