The peel of Florida oranges range in color from orange, or yellow-orange, to greenish yellow. The bright orange color so frequently associated with maturity, actually results from cooler night temperatures. Color is not an indication of ripeness. Florida oranges have thinner skins and may be yellow-green in color, but are sweet and juicy. They can actually turn orange and then back to green depending on temperatures. Ripe, juicy oranges feel firm and heavy, with skin texture ranging from smooth to pebbly.
