The title was named after the waka poem 'Being overwhelmed with grief, I'm wondering whether the color of the thin cloud over the ridges, which is covered by the rays of the setting sun, copied the color of the sleeves of my mourning dress.' that Genji composed in this chapter, mourning the passing of Fujitsubo.
巻名は作中で光源氏が藤壺の死を悼んで詠んだ和歌「入り日さす峰にたなびく薄雲はもの思ふ袖に色やまがへる」に因む。
