The phrase highlights a surprising historical fact: the earliest oranges, originally from Southeast Asia, were not the bright orange color we know today. Instead, they were green or yellow when ripe, especially in warmer climates. The familiar orange hue developed later through selective breeding and cultivation in cooler regions. This counterintuitive detail makes it sound unbelievable, but it’s a true example of how natural varieties can differ from modern expectations.

Why weren’t the first oranges orange?
Early citrus often ripened with green or yellow skins because chlorophyll remained visible; the iconic orange color comes from carotenoids that appear as fruit ripens, and climate and breeding influence this process.
Do oranges always turn orange when ripe?
No. In warm tropical climates ripe oranges can stay green; in cooler climates or with different varieties, the rind may turn orange as pigments develop.
What causes the color change from green to orange?
Ripening reduces chlorophyll and reveals carotenoids (like beta-carotene), giving the orange hue as pigments accumulate.
Where did oranges originate?
Oranges originated in Southeast Asia (parts of China/India region) and spread to other regions via trade, with later breeding producing the sweeter orange varieties we know today.
