Farrow & Ball

Imperial Purple

No. W40

Imperial Purple is a dark, muted purple with cool gray undertones that prevent it from reading as overtly violet. With an LRV of 32.5, it absorbs a good deal of light and works best in dining rooms, studies, or accent walls where a grounded wall color is the goal. The gray base softens the purple enough to sit alongside neutral schemes.

It pairs well with Shaded White and Slipper Satin for trim, while Hague Blue and Off-Black can deepen adjacent surfaces. Calluna offers a lighter purple for tonal layering.
