Uguisu-iro is a quietly poetic colour, and this limited edition fountain pen ink from Kyoto Ink captures it with admirable restraint. Inspired by one of Japan’s most cherished traditional hues, Uguisu-iro takes its name from the Japanese bush warbler, whose plumage is prized not for brilliance, but for subtlety.

Rather than a bold green, this ink reveals a gentle yellow-tinged green with earthy undertones—calm, natural, and deeply considered. It’s the sort of colour that rewards a second look, offering depth and warmth without ever demanding attention. Ideal for reflective writing, sketching, or design work where understatement carries more weight than spectacle.
