Be very leery of any published breakdowns for first gen Firebirds. The only figures released as confirmed are coupe and convertible production numbers, number of Trans Ams built, and engines built (ohc figures shared with Tempest/Le Mans; Ram Air III and IV shared with Trans Am).

Most other published figures are extrapolated from this data using best-guess technique. Until/unless all the PHS billing histories are entered into a database and sorted by model and year, there may never be accurate breakdowns of any option, including color.
