Describing something that tastes or smells like orange.
オレンジ refers to the sweet orange (Citrus sinensis), which is larger, often has a thicker rind, and may have seeds. みかん is the Japanese mandarin (Citrus unshiu), smaller, seedless, and easy to peel. In English, both are often called 'orange', but in Japanese they are distinct. Use オレンジ for the fruit typically found in Western supermarkets, and みかん for the winter fruit commonly eaten in Japan.
I bought both oranges and mikan at the supermarket.
When you want to be clear you're talking about the color, use オレンジ色. オレンジ alone can mean the fruit or the color, so context matters. In phrases like オレンジのTシャツ, it's understood as color because a T-shirt isn't a fruit, but オレンジ色のTシャツ is more precise.
The orange sunset is beautiful, isn't it?
このオレンジのTシャツが欲しい。
I want this orange T-shirt.
Traditional Japanese color name, literally 'bitter orange color'. Used in literature, art, and traditional contexts. Less common in daily speech.
