Stairway to Heaven in PPG

The closest PPG paint to Vista Paint Stairway to Heaven (0479) is Volcanic Ash 1012-6, a delta-E of 2.99 away — the nearest PPG makes, and near enough for most rooms, but it is not an exact copy.

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.
