The Kanji: 褐 (Katsu)
The kanji 褐 (read as katsu) primarily means "brown" or "coarse cloth." It is composed of the radical 衤(clothing) and 曷, reflecting its historical association with cheap, un-dyed garments made from hemp or burlap, which had a characteristic brownish color. This dual meaning connects a specific color with its humble origin in traditional clothing.
