cloud patterns, coloring of cloud
雯 centers on the visual beauty of clouds: their patterns, shapes, and coloring in the sky.
雯 combines 雨 (rain) with 文 (pattern, writing), suggesting patterned clouds or the coloring of clouds. The exact historical development is uncertain, but the component combination fits the meaning well.
Rain 雨 falling in patterned 文 streaks across the sky creates beautiful cloud patterns.
For ブン, imagine a bun-shaped cloud with intricate patterns: bun -> ブン, and the cloud's coloring makes it look like a decorated pastry.
