A refined, elegant vector logo centered on a clean, light grey background. The primary element is a sophisticated, ornate black calligraphic monogram of the letters 'C' and 'B' intertwined, contained within a delicate black oval frame. Above the oval frame sits a detailed black decorative ribbon bow with trailing ends. Below the framed emblem, the text "La Chambre Bleue" is set in a graceful black script font. Underneath this script, in a smaller, spaced-out, all-uppercase black sans-serif font, is the text "AIX EN PROVENCE". The entire composition maintains clean lines, precise shapes, and a high-end, traditional French aesthetic with absolutely no gradients or drop shadows. Aspect Ratio 1:1.
