Holden didn't keep such records. I've seen it commonly quoted for Ford's of the 70s, but if someone with a Holden says it they would be lying.

I believe for the HJ model the rarer colour combos to be found were during the last few months of production following the release of the LX torana but before HX Holden, were LX colours (which later became mainstays in HX) were then available on HJ - such as Aquarius and Papaya.
