All the Type 3 and Type 4 paint codes are shown with year and model in use, and a colour chip, which is reasonably close on my monitor. Type 34 Karmann Ghias generally used a different colour range, and some Beetle and Type 2 colours are not in this list.
If you are still in any doubt on the colour, after April 1970 the cars also had the factory 2-digit code stamped across the left end of the thin painted plate on one end of the front panel.
