Scientists have shown that the substances responsible for these colors actually help protect plants from chemical damage.

The pigments responsible for plant color belong to a class of chemicals known as antioxidants. Plants make antioxidants to protect themselves from the sun's ultraviolet (UV) light.

Factors affecting fruit color are primarily genetically determined. In addition, environmental factors such as nutrients, temperature and light conditions can have an effect on flavonoid composition and on the final hue of the fruit. In addition to flavonoids, carotenoids also give color to fruits. Concerning anthocyanins that are mainly responsible for the bluish to purple and reddish colors in plants, several different factors can affect the final color of the fruit or flower. Delphinidin-derived anthocyanins are known to be responsible for the bluish colors, whereas cyanidin -and pelargonidin-derived anthocyanins are found from mauve and reddish tissues, respectively. Anthocyanins readily form complexes with so-called co-pigments that can intensify and modify the initial color given by the pigment. Apparently, almost all polyphenols, as well as other molecules, such as purines, alkaloids and metallic cations, have the ability to function as co-pigments. Also, the temperature and pH of the vacuolar solution may affect the final color .
i hope its helpful

Fruits are described as ripened flower ovaries which produce seeds.

Plant pigments in fruits and vegetables are mainly chlorophylls (greens), anthocyanins (blues, purples, reds) and carotenoids (reds, yellows, oranges). In ten plant families that lack anthocyanins, the major fruit and flower pigments are betalains. The most familiar of these is betanin from red beet roots.

The orange in carrots is due to the carotenoid, carotene. The red in tomato is due to the carotenoid, lycopene. The red in red cabbage is due to anthocyanins that are pH sensitive. They are red in acid solution, purple in neutral, and blue in basic. A pH indicator can be made from a variety of anthocyanin containing fruits and vegetables, such as blueberries, cherries, blackberries, red onions, grapes and radishes.

Chlorophyll, xanthophylls, beta-carotene, carotenoids and some other pigments reflect photons of light to give different colors to leaves and fruits.All plant pigments are Porphyrin derivatives.

I believe it is due to their Phloem and outer bark fibers. It just happens to be what color they are. However, some fruits are brightly colored to attract creaters to eat them and speard their seeds,
