One Westminster tradition replicated in many times and places across the Commonwealth is a convention of colour: the lower house of a parliament is decorated in green, while the upper chamber is decorated in red. This reflects the green benches of the House of Commons and the red ones of the House of Lords.
Officially the plenary chamber of Quebec’s unicameral parliament is boringly the salle de l’Assemblée nationale but because of the colour of its walls it is more often known as the Salon bleu. One’s never surprised when Quebec bucks a trend or (more specifically) rejects an Anglo convention but it turns out the province’s plenary chamber did in fact used to be green until relatively recently.
When the members of the Legislative Assembly (as it then was) first convened in the Hôtel du Parlement in 1886 the walls were actually white. By the opening of the 1895 session the desks had been reappointed in green, but Le Soleil still made reference to the room as the “chambre blanche”. It was only in 1901 that the room was painted a “soft green” and the carpets and other furnishings changed accordingly. It even made an appearance in Alfred Hitchcock’s 1953 film “I Confess”.
From then the chamber was a Salon vert until 1978, when the decision was taken to begin broadcasting the proceedings of the Assemblée nationale.
The television specialists complained that the dark green of the chamber was not visually conducive to the TV cameras available at the time and, looking at the evidence from the 1977 test session (above), one can see their point. Walls of either beige or blue were the options recommended in an official report, and unsurprisingly the national colour was chosen.
The historian Gaston Deschênes has mentioned the technical requirements of broadcasting also coincided with a desire to break with a “British” tradition. Certainly the government of the day, René Lévesque’s Parti Québécois, didn’t mind the change, while Maurice Bellemare — “the old lion of Quebec politics” and sometime leader of the old Union nationale — was deeply pleased that the chamber adopted the colour of Quebec’s flag.
So the walls were repainted sky blue and the furnishings changed accordingly, resulting in the Salon bleu we know today (below).
A tweet from the Assemblée’s official account shows two photos looking towards the chamber’s entrance from before (above) and after (below) it was made ready for television.
All the same, green is not universal amongst Commonwealth lower (or only) chambers. It’s not even universal in Canada: Manitoba joins Quebec in its azure tones while British Columbia’s is red-dominated.
Quebec was the last of Canada’s provinces to abolish its upper house, the Legislative Council, in 1968 (at the same time the lower house was renamed the National Assembly). The Legislative Council’s former meeting place is, of course, red, and the Salon rouge is used for important occasions like inductions into the Ordre national du Québec or the lying-in-state of the late Jacques Parizeau.
Western Australia’s legislative assembly chamber is also blue, for reasons lost to history. All other Australian State lower chambers are green.
Western Australia’s lower house uses blue too I think, but it’s not a rejection of British tradition. Perth has suburbs where the UK-born proportion of the population comes close to 50%.
