The kanji 藍 primarily represents "indigo," a deep, vibrant blue dye derived from the indigo plant. It signifies both the plant itself and the color produced from it. The meaning extends to include anything related to the color indigo, like fabrics dyed with indigo, or even metaphorical uses representing depth and richness.

The kanji 藍 is a phono-semantic compound (形声文字, けいせいいもじ). The upper part represents a plant (艹, くさかんむり, "grass radical") and the lower part is 監, which contributes the phonetic element and originally conveyed a concept of "to look at." Thus, the character originally meant "the plant used to create a blue dye by looking at it closely," eventually coming to mean "indigo" itself.
