Parti national socialiste chretien

As to the colour of the flag, http://www.junobeach.org/e/2/can-eve-eve-fas-pns-e.htm says the following:

"The stage of the Monument National Theatre was decorated with four huge letters, the initials of the Party's name, PNSC, spelled out in small three-colour flags with the swastika. [...]"
Le Patriote, March 1, 1934 (in Jacques Lacoursière, Histoire populaire du Québec, 1997) (translation)

This might indicate the use of blue, white and red (the original French version call it "tricolore" as the French flag's nickname) tho not necessarily in the order mentioned by Znamierowski (who might have better source then us or might have guessed).
