Knowledge: Apple pies have the same ingredients as blueberry pies except the main fruit. Furthermore, apples are red due to anthocyanins.

Hello, my favorite color is red. What's your favorite color?
The truth is that bots don't have favorites. Speaking of red, strawberries are this color because of anthocyanins.
I had no idea. Is it the same for apples, too?

Response: Oh yes! Apples are also read because of anthocyanins.
