Whale'S Tail

16%LRV Value
Save

Whale'S Tail reads as crisp and architectural — strong in modern spaces, with natural fixed elements (chrome, stone, glass), or as a quiet anchor. At LRV 16 it reads as a deep, enveloping shade — best on accent walls, dining rooms, and spaces where atmosphere matters more than reflected light. Skip it if you want a cozy, warm room — cool neutrals can feel sterile under warm bulbs or in low light.

Whale'S Tail Technical Profile

What color is Dutch Boy Whale'S Tail (430-6DB)? It's a deep cool gray — hex #647074, LRV 16. The closest cross-brand equivalent to Whale'S Tail is Valspar Relaxed Navy — a near-identical match on the wall, with PPG Deep Iron Creek and Behr Rain Shadow also close. With an LRV of 16, Whale'S Tail creates a dramatic, enveloping mood — best on accent walls, dining rooms, and intimate spaces where atmosphere matters more than reflected light. As a cool neutral, Whale'S Tail pairs with cool whites for trim, gray-toned or rift-cut oak floors, and brushed nickel or polished chrome hardware. Black accents and natural greenery add contrast. As a deeper neutral, Whale'S Tail reads as a confident anchor — strongest on accent walls, cabinetry, and moody whole rooms that get enough natural light to keep it from going flat. Cool neutrals hold their crisp quality under 4000K+ daylight bulbs. Under 2700K warm light they soften considerably — particularly true for any blue or green undertone. Deeper neutrals can read close to black in low light, so preview Whale'S Tail in the room's actual evening lighting, not just at midday.
