red; red color
A traditional Japanese color name for a reddish-orange hue, often associated with cinnabar or vermilion. Less common in everyday speech than 赤 (あか), but still used in artistic, historical, or descriptive contexts.
この着物の丹色がとても美しい。
The red color of this kimono is very beautiful.
丹色の夕焼けが空を染めていた。
A red sunset dyed the sky.
丹 (に) refers to cinnabar or red earth, and 色 (いろ) means color. The combination directly yields 'cinnabar color' or 'red color'. The reading に is the native Japanese reading for 丹.
