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 anthocyanin also the reason Apples are red?

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