brown, woollen kimono
褐 centers on a coarse brown color, originally from undyed wool. The meaning extends naturally to a brown woolen kimono, which is a specific garment made from that material.
褐 combines 衤 (clothing) with 曷, which likely contributes the sound and may relate to coarse or rough material. The character originally referred to coarse woolen cloth or garments, and by extension the brown color of undyed wool.
The left side 衤 is clothing, and the right side 曷 looks like a person under a sunshade wearing a rough brown robe. Picture a monk in a simple brown woolen kimono.
For カツ, imagine a brown woolen kimono that is so coarse it feels like a cat's tongue: cat -> カツ, and the rough brown fabric matches the kanji's meaning.
