Cross-brand matchCross-brand matchBehr 640A-3 translated into the Farrow & Ball line
The closest Farrow & Ball paint to Behr Potentially Purple (640A-3) is Calluna 270, a delta-E of 9.24 away — the closest Farrow & Ball has, and far enough away that you should sample it before committing.
Calluna is 6.3 LRV points darker, so the room will read slightly deeper. Undertone reads as cool violet-gray against violet undertone, at chroma 3.3 and 12.0.
Codes are not transferable between manufacturers and no brand publishes a conversion table, so every figure here is measured from the published hex values rather than taken from a chart.
