Why is zucchini yellow?

Zucchini can be yellow due to a variety of factors, including the specific variety of zucchini being grown, the level of ripeness, and environmental conditions. Some zucchini varieties naturally produce yellow fruit, while others are green. Ripeness can also play a role, as zucchini that is left on the vine longer may turn yellow. Additionally, environmental factors such as sunlight exposure and soil composition can influence the color of zucchini.
