Orange 1970 Chrysler 300

Hi everyone,

On the fuselage.de website, there's a picture of an orange 1970 Chrysler 300, taken from the 1969 corporate annual report. As far as I can tell, it's not a color that was available in 1970. So was it a one off just for the report, or is there another story behind ?
