Grandeur Blue

4%LRV Value

Grandeur Blue reads as crisp and architectural — strong in modern spaces, with natural fixed elements (chrome, stone, glass), or as a quiet anchor. At LRV 4 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.

Grandeur Blue Technical Profile

What color is Dutch Boy Grandeur Blue (431-7DB)? It's a dark cool neutral — hex #313A45, LRV 4. The closest cross-brand equivalent to Grandeur Blue is Vista Paint In the Navy — a near-identical match on the wall, with Benjamin Moore Polo Blue and Behr Catwalk also close. With an LRV of 4, Grandeur Blue 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, Grandeur Blue 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, Grandeur Blue 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 Grandeur Blue in the room's actual evening lighting, not just at midday.

Grandeur Blue — Frequently Asked Questions

What colors match Grandeur Blue from other brands?
The closest cross-brand equivalents to Grandeur Blue are In the Navy by Vista Paint (a near-identical match), Polo Blue by Benjamin Moore (a near-identical match), Catwalk by Behr (a very close match). These are ranked with the CIEDE2000 color-difference formula, which scores how similar two colors actually look to the eye rather than matching them by name — so they're the best options for getting Grandeur Blue's look in a brand your local store carries. Always confirm with a physical sample, since sheen and lighting shift the final result.
What is the LRV of Grandeur Blue?
Grandeur Blue has a Light Reflectance Value (LRV) of 4.1, on a scale where 0 is pure black and 100 is pure white. That makes it a deep, dramatic color best saved for accent walls, dining rooms, and cozy spaces where atmosphere matters more than reflected light. LRV is the most reliable guide to how light or dark a paint will read in a real room — more dependable than the swatch on your screen, which varies by monitor.
