Turns out oranges develop chlorophyll as they mature on the tree. Then cool temperatures cause the chlorophyll to die off, turning the skins orange. But a sudden rise in temperature can turn them green, sometimes overnight. Especially near the equator, where temps are consistently high, ripe oranges are commonly green.
Is a green orange OK to eat?
A green orange is still great.
It turns out that you should never judge an orange by its skin color, which doesn’t give any indication of flavor or ripeness. “Cool nights can turn the fruit from green to orange, but a heat wave can turn the fruit back to green,” explains Nicole Jolly of the web series How Does It Grow?
Are green oranges real?
Fact is in most warmer parts of the world, especially around the equator, ripe oranges are green, never orange. As an orange matures, it is full of chlorophyll. If exposed to cool temperatures during the maturing process, chlorophyll will die off and the orange color comes through.
What does it mean when an orange is turning green?
This is because the green pigment chlorophyll is removed from the fruit, similar to what happens when the leaves of deciduous trees turn brown in the autumn. However, in tropical climates—like The Gambia—it is always hot so the chlorophyll is preserved and the skin of the oranges remains green.

This is the process by which plants obtain energy from the sun to grow and make life on earth possible.
Are green oranges not ripe?
Idiosyncrasies and Temperatures
Valencia oranges have a temperature-based idiosyncrasy that may make it appear that the oranges are not ripening. If ripened Valencias are hit with a warm spell, the skin may reabsorb chlorophyll, resulting in ripe oranges turning partially green.
Can you pick green oranges?
As mentioned above, color is not always an indicator of an orange’s ripeness. That said, you don’t want to pick green fruit. In many cases, the ripe fruit will simply drop from the tree.
