Thunderstorm in Benjamin Moore

The closest Benjamin Moore paint to Vista Paint Thunderstorm (0514) is Anchor Gray 2126-30, a delta-E of 1.48 away — close enough to swap without anyone noticing, though a large sample in daylight will show the difference.

Anchor Gray is 0.6 LRV points lighter, so the room will read slightly brighter. Undertone reads as blue cast against blue cast, at chroma 4.1 and 5.3.

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.
