ヤグルマギク
Its name is derived from the Ancient Greek κύανος, transliterated "kyanos", meaning "dark blue enamel, Lapis lazuli". It was formerly known as "cyan blue" or cyan-blue, and its first recorded use as a color name in English was in 1879. Further origins of the color name can be traced back to a dye produced from the cornflower ("Centaurea cyanus").
