Cook's Blue

Cook's Blue is a medium-toned cool blue that leans slightly toward ultramarine, tempered by subtle grey undertones. With an LRV of 54 it reflects a moderate amount of light and reads as clearly blue without becoming overly bright. It suits kitchens, utility rooms, or hallways where a distinct color is needed but full saturation would be excessive.

Pointing or Drop Cloth from Farrow & Ball work as adjacent neutrals to keep the scheme balanced. For contrast, pairing with darker tones like Railings or Studio Green adds definition, while Lulworth Blue offers a lighter tonal step within the same cool range.
