MC Book OUTTAKE #2: an early view of the same room, c. 1952
My opinion is that Madeleine chose the ruby red velvet on the walls and banquettes to complement the verdant green foliage outdoors. It wasn't long before the red was replaced by her signature blue trimmed with her Pompeian frieze border (renamed "Lola Montez" by Edmond Petit). The borne also received a similar make-over as you can see.
