Byzantine Blue works as a warm neutral anchor — pairs cleanly with most existing palettes and reads forgiving across lighting conditions. At LRV 32 it carries real depth without going dark — a good choice for accent walls, libraries, and rooms with abundant natural light. Skip it if you want a crisp, cool-modern look, or in rooms with heavy north light that can pull its warmth slightly muddy.

Byzantine Blue Technical Profile
What color is PPG Byzantine Blue (50BB 32/117)? It's a medium warm neutral — hex #9399B0, LRV 32. The closest cross-brand equivalent to Byzantine Blue is Dunn-Edwards London Fog — a very close match, with Valspar Twilight Fever and Dutch Boy Purplelicious also close. Its LRV of 32 gives Byzantine Blue depth without going dark, which makes it a strong choice for accent walls, libraries, and rooms with abundant natural light. As a warm neutral, Byzantine Blue pairs with off-whites for trim, white oak or walnut floors, and brass or warm brushed nickel hardware. Deep green, navy, or terra-cotta all read well as accent colors. At mid depth, Byzantine Blue grounds a space without darkening it — it holds up on lower walls, kitchen islands, and as a wraparound where a lighter neutral would feel washed out. Warm neutrals come alive under 2700K bulbs, where their underlying yellow or peach undertones add visible warmth. Under 4000K daylight they read cleaner and slightly cooler. At mid depth Byzantine Blue holds its character across bulb temperatures, shifting only slightly warm under 2700K and slightly crisper under cool daylight.
