You didn't say which orange so I'm going to guess that 524 Hugger/Red Orange is the shade of choice. So that gives us five possible stock color schemes.
524 solid orange
458 Deluxe Two-Tone with a white roof and between the belt and lower bodyside moldings. The "classic" Cheyenne paint scheme.
553 Conventional Two-Tone white roof only.
596 Special Two-Tone white roof and below the lower bodyside moldings (a Suburban scheme).
Then there is
565 Custom Two-Tone which would be a 524 orange truck with a black roof... factory.
As always custom arrangements and colors were available from the factory. Also in addition to the Hugger/Red Orange there was an International Orange (like Caltrans) and not to put too fine a point on it, a Yellow Orange
