KanjiJLPT N1
Indigo

Mnemonic

Pushing through tall grass on a hilltop, you oversee a sprawling valley of indigo plants. Workers below harvest leaves and plunge them into stone vats, and rivers of deep blue dye seep across the earth. From up here every acre glows with that unmistakable rich indigo hue.
Additional thoughts
Grass on top mirrors the radical's position atop the kanji. Overseeing from above ties the lower component to the act of surveying the dye fields. Picture yourself stained blue just from standing in that grass.
Quick recall
Standing in grass atop a hill, you oversee a valley steeped in indigo.

Details

The keyword for 藍 is indigo. This kanji refers to the indigo plant (*Persicaria tinctoria*), which has been cultivated in East Asia for centuries to produce a deep blue dye. By extension, it also refers to the rich blue color itself that is derived from this plant. In Japanese culture, indigo dyeing (*aizome*) holds a particularly important place in traditional textile arts, making this kanji closely associated with both the botanical source and its iconic hue.
