Oranges need cold night time temperatures to actually turn orange. When oranges are grown in tropical countries where the weather is always warm, their skin never turns orange, instead staying a leafy green colour even when fully ripe.
@InvaderXan This is amazing and I want green oranges now :3
@kellerfuchs
I think they usually tend to be sweeter? Something to do with warm growing conditions.
@hope @kellerfuchs
Yeah, that always bugs me too...
@InvaderXan do you know if that's true for mandarins too? We have a mandarin tree and they're starting to turn a bit orange but it is autumn where I live, I'm wondering if it's because of the colder temperatures or just a coincidence :)
@Some_Person
Truthfully, I’m not entirely sure. But that could be what’s happening, I think?
@InvaderXan that is interesting!
Do they taste the same?
@001zlnv
Yeah. Maybe a little sweeter from the warmer climate, but otherwise they’re just oranges.
@InvaderXan
They look unreasonably delicious. Is this related to the fact that most of the oranges in grocery stores have been dyed orange?
@anne
Oh, they don't dye them. Shop bought oranges are artificially orangified by exposing them to ethene gas. Conveniently, ripe bananas release lots of ethene...
