Little Blue Box in Behr

The closest Behr paint to Sherwin-Williams Little Blue Box (SW 9044) is Undine M450-4, a delta-E of 2.73 away — the nearest Behr makes, and near enough for most rooms, but it is not an exact copy.

Undine is 1.8 LRV points darker, so the room will read slightly deeper. Undertone reads as teal against green, at chroma 19.7 and 21.3.

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.
