Cook's Blue vs Naval
Cook's Blue is a Farrow & Ball color while Naval comes from Sherwin-Williams. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. At LRV 25 vs 4, Cook's Blue will read as the brighter of the two — a 21-point gap that matters most in north-facing or low-light rooms. They share a cool quality — useful to know if you're layering them in the same space. At ΔE 35.4, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 7 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cook's Blue vs Naval in Real Spaces
7 real rooms side by side. Seeing Cook's Blue and Naval in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Cook's Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that Cook's Blue will make the room feel meaningfully brighter than Naval would.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Cook's Blue will make the room feel meaningfully brighter than Naval would.
Home Office
In a home office, wall color sits in your peripheral vision for hours at a time, so temperature and undertone matter more than you might expect. The LRV gap is large enough that Cook's Blue will make the room feel meaningfully brighter than Naval would.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The LRV gap is large enough that Cook's Blue will make the room feel meaningfully brighter than Naval would.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Cook's Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. The LRV gap is large enough that Cook's Blue will make the room feel meaningfully brighter than Naval would.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
