Infact
84 / 100
True

Oranges are not always naturally orange and can stay green when ripe due to weather. Farmers use Citrus Red No. 2 dye or ethylene gas to change their color.

Infact verdict: True (84/100).

The claims about oranges' color and the methods used to alter it are largely supported by the evidence. Oranges can remain green in tropical climates due to the lack of chlorophyll breakdown, and ethylene gas is used to change their color. Citrus Red No. 2 is used in the U.S. to dye orange peels, although it is controversial and being phased out. Overall, the claims are factual with some regional and regulatory nuances.
