Do tomatoes turn green then red?

Tomatoes actually start green and then turn red (or other colors depending on the variety).

Here's why:

* Chlorophyll: When tomatoes are growing, they have a lot of chlorophyll, which gives them their green color. This chlorophyll helps the plant photosynthesize.

* Lycopene: As the tomato ripens, the chlorophyll breaks down and the red pigment, lycopene, becomes more prominent.

* Color change: The change from green to red (or other colors) indicates the tomato is becoming ripe and sweeter.

So, the answer is no, tomatoes don't turn green then red. They start green and gradually turn red (or other colors) as they ripen.
