What color is Farrow and Ball Cook's Blue?
Farrow and Ball Cook's Blue 237 is a mid-tone blue with a softened, slightly greyed cast that keeps it from looking overly bright. Its cool character is clear, though the muted finish gives it enough depth for larger wall areas. In daylight, this color reads as a clean but restrained blue; under warmer evening lighting, it can appear gentler and a little more subdued. It suits bathrooms, bedrooms, and painted kitchen cabinetry, especially alongside crisp white trim, pale stone, or brushed nickel. Pair Cook's Blue with natural oak, light grey textiles, or warm off-whites to bring out its balanced, practical quality.

What are Farrow and Ball Cook's Blue undertones?
Cook’s Blue reads as a midtone, moderately muted blue with clear color presence rather than a pale or greyed-out look. Within the blue family, the supplied digital sample has a slight green-leaning bias, which gives it a cleaner, cooler cast than a violet-leaning blue; this is a relative visual assessment, not a statement about the paint’s pigments. Warm artificial light may make it look a little softer and less cool, while cool daylight may make its blue-green direction more noticeable, depending on the room and surrounding surfaces.

LRV of Cook's Blue
Cook's Blue has an LRV of 25.1% and refers to Medium colors that reflect a lot of light. Why LRV is important?
Light Reflectance Value measures the amount of visible and usable light that reflects from a painted surface.
Simply put, the higher the LRV of a paint color, the brighter the room you will get.
The scale goes from 0% (absolute black, absorbing all light) to 100% (pure white, reflecting all light).
Act like a pro: When choosing paint with an LRV of 25.1%, pay attention to your bulbs' brightness. Light brightness is measured in lumens. The lower the paint's LRV, the higher lumen level you need. Every square foot of room needs at least 40 lumens. That means for a 200 ft2 living room you'll need about 8000 lumens of light – e.g., eight 1000 lm bulbs.
