Orange

Orange (fruit)

The orange, also called sweet orange to distinguish it from the bitter orange, is the fruit of a tree in the family Rutaceae. Botanically, this is the hybrid Citrus × sinensis, between the pomelo and the mandarin orange. The chloroplast genome, and therefore the maternal line, is that of pomelo. Hybrids of the sweet orange form later types of mandarin and the grapefruit. The sweet orange has had its full genome sequenced.

Orange blossom

The orange blossom is the fragrant flower of the Citrus sinensis. It is used in perfume making and has been written about as an aphrodisiac. Orange blossom essence is an important component in the making of perfume. The petals of orange blossom can also be made into orange flower water, a common part of both French cuisine and Middle Eastern cuisine. It's also present in Hispanic culinary traditions, with notable examples being Mexican pan de muerto and Spanish Roscón de Reyes.

Orange (colour)

Orange is the colour between yellow and red on the spectrum of visible light. The human eyes perceive orange when observing light with a dominant wavelength between roughly 585 and 620 nanometres. In traditional colour theory, it is a secondary colour of pigments, produced by mixing yellow and red. In the RGB colour model, it is a tertiary colour. It is named after the fruit of the same name.
