Prost Grand Prix
Blue is France's national racing colour; therefore, several French motorsport teams have used it, including Alpine, Amilcar, Ballot, Bugatti, Delage, Delahaye, Gordini, Ligier, Mathis, Matra, Panhard, Pescarolo Sport, Peugeot, Prost Grand Prix, Rondeau, Salmson, Talbot-Lago, Voisin. The two notable exceptions are Citroën and Renault: the former has used red and white, whereas the latter has used yellow and black. Between and Renault F1 cars wore a blue colour not as the national racing colour of France but due to the team´s title sponsor the Japanese brand of cigarettes Mild Seven. Blue will return to the factory Renault F1 team for 2021, as the team renames to Alpine.
