The closest Sherwin-Williams paint to Vista Paint Thunderstorm (0514) is Outerspace SW 6251, a delta-E of 1.73 away — close enough to swap without anyone noticing, though a large sample in daylight will show the difference.

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.
