Obsidian Hex is a bold geometric black grasscloth wallpaper in dark charcoal-brown, its interlocking hexagonal basket pattern built from two alternating surface finishes: smooth wood-grain-like strips and fine open-weave crosshatch sections. The result is a near-matte, tactile surface that reveals its construction up close and reads as a continuous dark geometric field from across the room. Produced with our partner mills to this studio design, Obsidian Hex is supplied to interior designers, hospitality specifiers, and trade buyers from 50 rolls.

How Two Surface Finishes Build This Geometric Field

  • The hexagonal basket is formed by bands intersecting at approximately 60-degree angles, creating repeating hexagonal cells across the surface.
  • Alternating bands carry two distinct surface finishes: smooth wood-grain-like strips and fine open-weave crosshatch sections.
  • At close range the two textures are clearly distinct; at room distance (3 m and beyond) the surface resolves into a unified near-black geometric field.
  • The bold scale of the hexagonal unit keeps seam interruptions minimal across large walls compared to fine-weave patterns.
  • The fully matte finish ensures consistent colour under artificial lighting, with no hot spots or reflective variation regardless of beam direction.

Each band of the hexagonal basket intersects at approximately 60-degree angles, forming a repeating geometric field across the surface. The alternating strip finishes (one smooth and wood-grain-like, one fine and crosshatch-textured) create a surface that shifts character depending on viewing distance. At arm's length, the two textures are clearly distinct; at three metres or more, the eye resolves them into a unified near-black geometric pattern, the hexagonal structure prominent but individual elements no longer competing. The bold scale of the unit keeps seam interruptions minimal across large walls, and the fully matte finish ensures the surface holds consistent colour under artificial lighting without producing reflective variation.

Candlelight, Low Voltage, and Afternoon Shade: What Black Grasscloth Does to Light

  • Dark-value grasscloth absorbs rather than reflects, lowering perceived brightness and increasing the sense of spatial enclosure.
  • Under directional grazing light from wall-washers or angled pendants, the smooth and crosshatch surface finishes separate visibly: smooth strips catch the angle marginally more than the crosshatch sections.
  • Under diffuse overcast daylight, both surfaces hold as near-uniform charcoal, giving the room a composed, settled quality.
  • Under warm tungsten or candlelight, the warm undertone in the charcoal-brown becomes slightly more present, shifting the surface toward very deep espresso.
  • Best specified in rooms where lighting is controlled and designed rather than ambient-only: hotel bars, private dining rooms, suites with blackout capability.

Dark-value grasscloth absorbs rather than reflects, which lowers perceived brightness and increases the sense of spatial enclosure in any room where it is used. Under directional grazing light from wall-washers or angled pendants, the two surface finishes begin to separate: the smooth strips catch the angle of light marginally more than the crosshatch sections, introducing a quiet tonal variation within the pattern that is perceptible in person but rarely apparent in photographs. Under diffuse overcast daylight, both surfaces hold as near-uniform charcoal, giving the room a composed, settled quality. Under warm tungsten or candlelight, the warm undertone in the dark charcoal-brown becomes slightly more present, shifting the surface toward a very deep espresso. Black grasscloth wallpaper at this value works best in rooms where lighting is designed and controlled rather than ambient-only.

Rooms That Ask for Weight: Hotel Lobbies, Private Dining, and the Dark Envelope

  • Hotel lobby and reception feature walls: the bold geometric pattern creates a resolved graphic backdrop without requiring additional ornament.
  • Private dining rooms: the dark ground reduces the need for further decorative layering and works with candlelight rather than against it.
  • Residential studies, home bars, and principal bedrooms used primarily in the evening.
  • Hotel suite headwalls, particularly where the lighting scheme concentrates on bedside fixtures rather than an overhead ambient wash.
  • For rooms with limited natural light, request a sample and assess it under the proposed artificial scheme before specifying at scale.

Black grasscloth wallpaper performs most convincingly in spaces where designers are building enclosure, lowering perceived ceiling height, or creating a setting that reads as deliberately interior. In hotel lobbies, it holds a reception or feature wall without requiring additional ornament; the geometric scale of the pattern provides visual resolution from across a large space. Private dining rooms benefit from the dark ground because it reduces the need for further decorative layering while working with rather than against candlelight. Residential studies, home bars, and hotel-suite bedrooms where lighting focuses on bedside or reading sources rather than ambient overhead wash suit this pattern well. For any room with limited natural light, request a sample and view it under the actual proposed artificial scheme before committing to a full specification.

Anchoring a Dark Palette: Materials That Sit Beside Black Grasscloth Wallpaper

  • Brass fittings and hardware echo the warm undertone in the charcoal-brown, integrating naturally rather than contrasting.
  • Travertine and cream or veined marble in flooring and horizontal surfaces provide the sharpest value contrast and give the eye a resting point.
  • Pale or bleached oak in cabinetry and joinery softens the palette at the perimeter without competing with the wall plane.
  • Blackened-steel frames, shelving, and hardware carry the dark tone into the room's three-dimensional elements as a tonal extension.
  • Bouclé or linen upholstery in oat, cream, or warm grey completes the layering; mid-tone browns in upholstery or flooring tend to flatten the contrast the dark ground creates.

  • Sample books available at a fee credited against confirmed orders (up to 10% of order value).
  • Three in-house designers convert your references and mood boards into CAD specifications for production with our partner mills.

  • Orders proceed on a deposit basis, with the balance due before shipment; all freight at buyer's cost on FOB, CIF, or DDP terms.
  • Every production run ships as a single dye lot; per-batch lot certificates issued to support documentation requirements.

A physical sample is the starting point for any specification: samples are dispatched to trade buyers and designers so the surface can be assessed under real project lighting before any commitment is made. Sample books are available at a fee credited against confirmed orders (up to 10% of order value).

Frequently asked

Will this very dark charcoal colour show fading near windows?
Dark-value grasscloth is more susceptible to uneven UV bleaching than lighter colourways — a near-black surface that fades in patches will show it clearly. For south- or west-facing exposures, we recommend UV-filtering glazing or placing this pattern away from prolonged direct sunlight. Additional samples are available for an in-situ light-exposure test before you specify.
How do seams read on a bold geometric weave at this scale?
Because the hexagonal basket pattern has a strong directional repeat at a bold scale, seams require careful alignment during installation. Reverse-hanging alternate drops is standard practice for grasscloth; for a geometric pattern of this weight, we recommend engaging an installer experienced with repeat-matched natural wallcoverings and carrying out a test panel before the full installation proceeds.
Is black grasscloth wallpaper suitable for hotel lobbies or corridors with heavy foot traffic?
Grasscloth is a natural-fibre wallcovering and is not intended for surfaces subject to direct contact or abrasion. In lobbies and corridors it performs well when specified above dado height or as a feature wall with adequate setback from high-contact zones; for areas requiring scrubbable or impact-resistant surfaces, verify specification requirements before selecting a natural wallcovering.
What is the minimum order quantity for this pattern?
Custom colourways require a minimum of 50 rolls (approximately 250 m²); stock patterns may be available in smaller quantities for first trials, and full ordering details including lead times and payment terms are on our [process and FAQ page](/faq).
