An orange is a citrus tree that produces sweet-smelling white blossoms, and eventually, oranges. Orange, as in the bright color, comes from the name of the fruit and tends to be used for items we need to notice: like road construction signs and prison jumpsuits.
Oranges grow in warm places like Florida, California, and Brazil, where they are harvested to be eaten and made into juice and other products. The color of the orange, in varying hues, is also orange, a warm, sunny shade that falls between red and yellow on the color spectrum. The first orange trees probably grew in India, and the word itself has its roots in the Sanskrit naranga-s, "orange tree."
