As some leaves die, they produce chemicals called anthocyanins (also found in the skin of grapes and apples) from built up sugars. These chemicals produce a red color that can be combined with green color from the chlorophyll plant to create different shades of red.
The leaves also produce compounds called carotenoids, which are responsible for the red color of carrots and other fruits and vegetables. They are produced by the chloroplasts of the leaves and can be used as a source of vitamin A and beta-carotene.

The difference between red and yellow is not so much a difference in color, as in how they are produced. Melanin is a type of pigment that is made up of many different types of pigments. It is present in all living things, including plants, animals, fungi, bacteria, viruses, etc. When a red pigment is exposed to sunlight, it turns into a yellow pigment.
This process is called photoprotection. Yellow is also produced when the sun’s rays are absorbed by chlorophyll, an organic molecule that forms the basis of photosynthesis in plants and animals.
