HELP PLEEAAASSE ITS NOT AS BAD AS IT LOOKS I PROM ISE ITS PHYSICAL AND CHEMICAL CHANGE

Sara learns from a book that, as fall turns to winter, leaves change color. This happens because as the weather turns colder, the chlorophyll in the leaf breaks down, the green color disappears, and the yellow to orange colors become visible. Sara wants to show her class how the leaves change but it is still springtime. She paints a leaf orange to show how the leaves change color.

How is painting a leaf orange different from the color change that happens during the change of seasons if both result in an orange leaf at the end?
