First the Fruit, then the Color!
The fruit 'orange' came before the color name was coined. In the 14th century, orange was actually 'narrange' which lost its 'n' in the process of wrong word division.

Orange juice is a healthy drink made from fresh oranges without fermentation. Drinking orange juice benefits your body with a number of useful properties. The juice is the richest source of vitamin C, and you can fulfill your daily quota of vitamin C by just drinking a single serving of orange juice. It contains good content of various useful minerals like potassium and magnesium, is low in fats, and contains no cholesterol. Fresh orange juice is difficult to store, and hence, you should never rely on packaged orange juices. They contain preservatives and have more calories as compared to homemade fresh orange juice.
