About these colors:
Color names, factory paint codes, and production years are cross-referenced from established
marque references and owner registries. Hex codes are approximate digital representations of
factory paint — vintage automotive paint was never defined as a hex value, and original enamel
fades over time. True paint colors depend on age, sun exposure, refinishing history, and
production batch variation. For an accurate match, always mix by the factory paint code — not
by the on-screen swatch — and verify against an original paint chip or a professional
color-matched sample before purchasing paint for a restoration.
