Palace Blue
What Palace Blue Actually Looks Like
Palace Blue CW-605 sits in medium-value territory, a teal-leaning blue with enough gray in it to keep things grounded rather than vivid. It reads as a composed, aquatic blue in most conditions, the kind of color you associate with 18th-century interiors and well-worn seaside buildings. It is not a bright or electric blue. The gray content softens it considerably, and the overall effect is calm and deliberate.
Palace Blue Undertones
The color carries clear green-leaning teal undertones beneath its blue base. That teal quality means it can shift depending on what surrounds it. Next to warm whites or wood tones, the cool blue reads more prominently. Next to true greens, the blue side asserts itself. In rooms with limited natural light, it can settle into a deeper, more muted slate-blue. In strong north light it may lean slightly green. South- or west-facing rooms with warm afternoon light tend to pull out the blue most cleanly.
Where Palace Blue Works Best
Palace Blue is part of Benjamin Moore's Colonial Williamsburg collection, so it carries a built-in affinity for traditional architecture: paneled rooms, built-ins, formal dining rooms, center-hall entries, and exterior shutters or doors on period homes. That said, the gray content keeps it from feeling costume-y, and it translates well to transitional spaces too. On cabinetry it reads classic and considered. On a front door it makes a confident statement without going full navy. It is available in both interior and exterior formulas, which broadens where you can use it meaningfully.
Where to put Palace Blue
A formal dining room is one of the strongest fits for Palace Blue. The medium value reads rich under candlelight or warm-bulb fixtures, and the historical provenance of the Williamsburg palette feels at home in a dressed-up space. Use it on all four walls with white trim for a classic, envelope effect.
In a center-hall entry, Palace Blue sets a clear tone the moment you walk in. Keep the ceiling lighter, use a warm-toned floor, and the color will feel anchored rather than cold. It handles varying light conditions reasonably well in a transitional space that sees both natural and artificial light throughout the day.
The composed, slightly receding quality of this blue makes it good for a room where you want to feel focused. Pair it with dark wood shelving and aged metal hardware. In a north-facing office it will deepen and lean slightly green-blue, so test a large sample before committing.
Palace Blue is available in an exterior formula, and on shutters or a front door against a white or cream body, it delivers the kind of classic curb appeal that suits Colonial, Federal, and Cape Cod architecture particularly well. In direct sun it will read brighter and bluer; in shade it deepens noticeably.
On kitchen or bathroom cabinetry, Palace Blue works best with warm countertop materials like butcher block, honed marble, or warm-veined quartzite. Brass or unlacquered hardware reinforces the historical character. With very cool white countertops and chrome hardware, the color can feel a bit flat, so warm up at least one element.
What to Pair With Palace Blue
Because Palace Blue CW-605 has no Benjamin Moore coordinating colors assigned in this collection, pairing guidance here is based on its color behavior. Lean toward warm or creamy whites to counterbalance the cool teal undertone, and use natural wood tones or aged brass hardware to keep the space from feeling cold.
Colors that clash with Palace Blue
In a north-facing room already starved of warm light, Palace Blue can tip from calm to cold. The teal undertone becomes more pronounced and the overall effect can feel clinical rather than composed.
A stark, blue-white trim color can amplify the cool side of Palace Blue and make the combination feel stark rather than crisp.
At LRV 33, this is a medium-dark color, and a high-gloss finish on walls will reflect light unevenly, highlighting every imperfection in the drywall and intensifying the color in ways that can feel overwhelming in a large room.
Common questions
The Benjamin Moore code is CW-605, the hex is #5D9FB6, and the LRV is 33.34. That LRV places it in medium-dark territory, meaning it will absorb a noticeable amount of light and read richer as a room gets larger.
Yes. It is available in both interior and exterior Benjamin Moore formulas, which makes it a practical choice for shutters, front doors, and other exterior trim elements on period-appropriate homes.
It can. The teal component in its undertone means that in north-facing rooms, under cool fluorescent or daylight-spectrum lighting, or next to warm colors that push the contrast, it may read with a noticeable green cast. Test a large sample in your specific room and lighting before committing.
A satin or semi-gloss finish holds up to cleaning and gives cabinetry a clean, slightly refined look. Semi-gloss will intensify the color slightly, so if you have already tested the color on walls in eggshell, expect it to read a touch richer on cabinets.
