I purchased these Pas de Calais soft sarouel pants in 2017 for 17,000 yen + tax. The color is black. Pure black. The fabric is thin, with a formal feel, like that used for suits. It's difficult to see, but the first image is the front, and the second image is the back. These are versatile pants that can be worn casually or in a more polished style. They can be worn for three seasons, excluding winter. I look forward to your consideration.
