Narrative:

Runway 28 active per ATIS and taxied on parallel taxiway from GA ramp. Advised tower ready to go upon reaching runway. Cleared for takeoff prior to reaching hold short line. Checked for inbound traffic as a matter of habit. Rolled onto runway and completed runway check. Gradually applied power. After departure both PIC and sic realized error of departure on runway 32 instead of runway 28. We were advised by tower on climb out, given a heading and handed off to departure. No conflicting traffic on either runway. Failure to closely examine airport diagram led to taxiway confusion. Assumed hold short line was for departure runway which we were cleared onto. Instruments and directional gyroscopes had been set on taxiway. Failure to reconfirm heading after taxiing into departure position. Runway numbers obscured by patch snow.
