Farrow & Ball

Book Room Red

No. 50

Book Room Red is a warm, muted red with noticeable brown undertones that keep it from reading too bright or primary. With an LRV of 45.3, it sits in the mid range and can darken noticeably in rooms with limited natural light. It is commonly used in libraries, dining rooms, and more traditional interiors where a deeper wall color is appropriate.

For a warm, grounded scheme, it pairs with Farrow & Ball's London Clay and Tanner's Brown, while Joa's White or Pointing can lighten trim and ceilings. For cooler contrast, Light Blue or Borrowed Light offsets its warmth effectively.
