Light Reflectance & Undertone
Light Reflectance Value (LRV)
1/100
Very Dark
Absorbs almost all light — dramatic and cocooning. Needs strong artificial lighting and works best as an accent or in well-lit rooms.
Undertone
Reads as a cool blue with a violet undertone showing through, especially in daylight. Pair trim and adjacent colours to either calm or amplify that undertone.

Color Psychology
Focused · Cooling
Blue lowers the temperature of a room — useful in south-facing rooms that overheat visually, and in home offices where you want a clear head. Pair with warm wood and brass to keep it from reading clinical.

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.
