Farrow & Ball Acid Drop No. 9908 is a part of the archived collection.

Acid Drop, as its name suggests, is a bright and energetic citrus shade. Lime green with a hint of warming yellow, it captures the same zingy thrill as the intensely sour boiled sweet after which it’s named, especially when combined with the equally vibrant Charlotte's Locks.

Archived colors can still be mixed in-store; however, sample pots are discontinued, and are only available while supplies last.
