To me, the color does resemble that of cat poop; hardly one to paint a bedroom in; but maybe a cell for ISIS terrorists or serious masochists.
Given those kinds of associations, it it surprising that opaque couché can serve as a fashion statement:
Risk-taking and edginess have always been in the world of couture; but this is certainly a bold move! Wearing red or yellow is regarded as a bold statement, not without risks. But the woman who wears an opaque couché garment radiates a confident message: "I'm so beautiful and charismatic that I can dare to wear a dress that is the color of cat or baby poop!"
