Citadel

Benjamin Moore · CC-936

The Analysis

Citadel is a mid-toned slate blue that absorbs more light than it reflects, given its 37.19 LRV. It creates a cozy, contained feeling in a room rather than making it feel expansive or airy.

It works best as a moody backdrop or a sophisticated main wall color in smaller, dedicated spaces. Because it is a saturated mid-tone, it acts as a strong anchor that makes other furniture pieces pop.

History & Origin

Citadel leans into a modern, tailored aesthetic rather than a specific period look. It fits well in contemporary renovations that prioritize structured, clean-lined design over ornate details.

How to Use It

Use this in bedrooms or home offices paired with warm walnut wood tones to balance the cool blue. For hardware, matte black provides a sharp, modern contrast, while unlacquered brass adds a touch of warmth.

The Mood

This shade promotes a grounded, calm atmosphere that feels stable rather than stimulating. It is an excellent choice for areas where you want to signal to your brain that it is time to relax or focus.

Colour harmonies

Complementary

Opposite on the colour wheel — bold, high-contrast pairings. Use for a feature wall or furniture you want to command attention.

Analogous

Neighbouring hues — cohesive and calm, great for layered schemes that feel collected rather than matched.

Split complementary

Near-opposites for strong contrast with a little less tension than a pure complement. A favourite of interior designers.

Triadic

Three evenly spaced hues — balanced, vibrant, and versatile. Keep one dominant and use the others sparingly.

Tetradic (square)

Four hues in a square on the wheel — rich, dynamic palettes. Best when one colour leads and the others accent.

Monochromatic

Dark, mid, and light steps on the same hue — a failsafe gradient for trim, walls, and accents without shifting colour family.
