brown tinged with olive green and indigo
A traditional Japanese color name (和色名) describing a muted, complex brown with olive-green and indigo undertones. Rarely used in everyday conversation; mainly encountered in contexts of traditional arts, dyeing, or historical color charts.
Aimirucha is one of the color names used in dyeing during the Edo period.
海松茶 (mirucha) is a related traditional brownish-green color name; 藍海松茶 adds an indigo (藍) nuance, making it a darker, more bluish-brown.
Compound of 藍 (ai, 'indigo'), 海松 (miru, a type of seaweed), and 茶 (cha, 'brown/tea color'). The name likely describes a color reminiscent of indigo-dyed seaweed brown. The exact historical origin is uncertain.
