Parma in PPG

The closest PPG paint to Vista Paint Parma (8642) is Sweet Peach 1065-4, a delta-E of 1.92 away — close enough to swap without anyone noticing, though a large sample in daylight will show the difference.

Light reflectance is effectively identical, 54.0 against 54.0. Undertone reads as red against red, at chroma 15.6 and 14.8.

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.
