 Traditionally , Edinburgh Corporation , Lothian Regional Transport and Lothian Buses had a livery of madder ( a dark red ) and cream , with matching madder leatherette seating . Some coach @-@ seated Alexander RH bodied Leyland Olympians and Alexander Royale bodied Volvo Olympians were painted in the same scheme , but with red in place of the madder . These vehicles are not branded for , but usually operated only on routes 15 / 15A .
