Rich Cobalt is a calming choice — works as both a whole-house neutral when lightened and a dramatic anchor when deepened to navy. At LRV 8 it reads as a deep, enveloping shade — best on accent walls, dining rooms, and spaces where atmosphere matters more than reflected light. Because it's a fully saturated example, it lands strongest as a single accent wall or large architectural feature rather than the dominant whole-room color. Skip it in low-light north-facing rooms unless you want a deliberately cool, cocooning effect, since blue can read chilly there.

Rich Cobalt Technical Profile
What color is Dutch Boy Rich Cobalt (139-7DB)? It's a dark warm blue — hex #225288, LRV 8. The closest cross-brand equivalent to Rich Cobalt is Sherwin-Williams Frank Blue — a near-identical match on the wall, with Behr Express Blue and Kilz Navy Dress also close. With an LRV of 8, Rich Cobalt creates a dramatic, enveloping mood — best on accent walls, dining rooms, and intimate spaces where atmosphere matters more than reflected light. Pair it with cool whites like Chantilly Lace, walnut or rift-cut oak floors, and brushed nickel or polished chrome hardware. Brass accents add warmth for a layered look. As a fully saturated example, it reads as a confident statement color — best deployed as a single accent wall or large architectural feature rather than a whole-room dominant. Blues stay crisp under 4000K+ cool LEDs. Under 2700K warm bulbs they can read grayer or shift slightly purple — particularly true for mid-tone and saturated blues. Saturated colors amplify lighting effects more than muted ones: warm bulbs deepen and enrich, cool daylight sharpens and slightly cools the same hex.
