Similarly, the hues of autumn leaves are from the same pigment after chlorophyll is removed. These pigments convert the light energy that the plants absorb from the Sun into chemical energy for the plants' growth. The orange colour of many fruits and vegetables, such as carrots, pumpkins, sweet potatoes, and oranges, comes from carotenes, a type of photosynthetic pigment. It is named after the fruit of the same name. In the RGB colour model, it is a tertiary colour. In traditional colour theory, it is a secondary colour of pigments, produced by mixing yellow and red.
