Seawater Blue 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. Skip it in low-light north-facing rooms unless you want a deliberately cool, cocooning effect, since blue can read chilly there.

Seawater Blue Technical Profile
What color is Dutch Boy Seawater Blue (235-7DB)? It's a dark cool blue — hex #2C5264, LRV 8. The closest cross-brand equivalent to Seawater Blue is PPG Plymouth Blue — a near-identical match on the wall, with PPG Regatta Bay and Sherwin-Williams Marea Baja also close. With an LRV of 8, Seawater Blue 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. At mid saturation, this color sits at a flexible mid-point — bold enough to anchor a room without dominating, and pairs cleanly with both crisp and creamy whites. 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. At mid saturation the lighting shift is moderate but real — sample under both warm-bulb evening light and cool-daylight morning light before committing.
