Color Psychology
Quiet · Versatile
Underworld gets out of the way so the architecture and the people in the room do the work. The right neutral is never a default — it reads warm or cool, dusty or sharp depending on its undertone, and that undertone is what makes or breaks the room.

Paint Info
Brand · Product Line
Benjamin Moore / Aura Interior (for richer color depth in deep tones)
Recommended Finishes
Matte (walls) · Pearl (trim) · Satin (doors)
Deep colors look best in matte — gloss exaggerates surface flaws. Reserve subtle sheen for trim, doors, and high-touch areas.
Best Surfaces
Accent walls · Doors · Cabinetry · Built-ins
Coverage & Dry Time
Typical coverage 350-400 sq ft per gallon over a primed surface.
Touch-dry in ~1 hour. Recoat after 4 hours. Full cure 7-14 days.
Primer
Tinted primer in a similar value is highly recommended — saves a coat and prevents the wall colour from washing the surface.
Application Tip
Use a 9" microfiber roller on walls and a 2.5" angled sash brush for trim cuts. Two coats minimum for even depth.
