Prussian Blue
What Prussian Blue Actually Looks Like
Prussian Blue CW-625 is a deep, saturated blue that reads as a true navy in most interior light. It carries real depth without tipping into black, and in bright daylight it opens up enough to show a clear, assertive blue character. In dim or artificial light it darkens noticeably and can feel almost charcoal-blue. It is not a bright or electric blue. It is the kind of color that grounds a room with quiet authority.
Prussian Blue Undertones
The color sits in cool-to-neutral blue territory. There is no strong green lean and no obvious purple pull. Because it is a Colonial Williamsburg shade, it carries a historically grounded, slightly muted quality rather than a clean, modern cobalt. In warm incandescent light a faint warmth can surface, but the dominant read is cool and composed.
Where Prussian Blue Works Best
CW-625 works well on exterior shutters and front doors, where its depth holds up in full sun and reads as a classic, considered choice against white or cream trim. Indoors it suits a study, library, or dining room where a cocooning atmosphere is the goal. It is also a strong candidate for cabinetry and built-ins, where a high-quality finish will bring out the richness of the pigment. Use it where you want color to do structural work, anchoring a space rather than brightening it.
Where to put Prussian Blue
In a dining room, Prussian Blue creates a deeply enveloping backdrop that makes candlelight and warm overhead fixtures glow. It works especially well if the trim is a crisp white or warm cream, giving the eye a clean boundary and preventing the space from feeling heavy.
The color is well suited to a study or library where the goal is focus and enclosure. Floor-to-ceiling bookshelves in natural wood or white against this wall color feel intentional and calm. Artificial light keeps the color readable through the day.
As a Colonial Williamsburg shade, Prussian Blue has strong historical precedent on exterior woodwork. On shutters or a front door against a light-colored house, it reads as classic and polished without being trendy. Full sun will lighten its appearance slightly, keeping it from looking too heavy outdoors.
On lower cabinets or an island, this color grounds the kitchen and pairs naturally with brass or unlacquered bronze hardware. Keep upper cabinets light to balance the room and avoid a closed-in feeling.

Colors that clash with Prussian Blue
Pairing Prussian Blue walls with cool gray or blue-gray flooring can flatten the room, removing contrast and making the overall palette feel monotone and cold.

A stark, blue-white trim can amplify the cool quality of Prussian Blue and make the overall scheme feel clinical rather than classic.
Common questions
The color code is CW-625, reflecting its place in the Colonial Williamsburg collection. The LRV is 12.17, which confirms this is a genuinely dark color that absorbs most of the light in a room. The hex and RGB values render from our color fields above.

Yes, noticeably so. In bright natural daylight it reads as a clear, deep blue. Under warm incandescent or Edison-style bulbs it shifts slightly warmer and darker. In north light or low ambient conditions it can approach a near-charcoal blue. Sample it in the actual room across different times of day before committing.
For walls, an eggshell finish is a practical choice. It is easy to clean and adds just enough sheen to keep the deep color from feeling flat without creating distracting reflections. For cabinetry or trim, a semi-gloss or satin finish will bring out the depth of the pigment and hold up to daily use.
