Brightly coloured flowers are normally pollinated by any number of animals and insects. The coloring acts as an attractant to the flower which normally then offers nectar as an additional attractant.
Dull coloured flowers (or white ones) are normally attracted to nocturnal animals (bats, mice etc) as well as nocturnal insects such as moths. They also normally have a strong scent as an added attractant.

Overall brightly colored flower petals assist in attracting insects, birds and small mammals to the flower for pollination. Coloured petals and nectar are normally used in conjunction - the petals as the attractant and the nectar as the "reward". Some petals which are not brightly coloured to humans, but reflect light in the Ultraviolet spectrum which some insects and birds can see.
they have this to attract insects to the pollen.
Brightly colored petals serve to attract animals to the flower - the nectar the flower produces is a reward for the animals moving pollen from one flower to another and pollinating them. Animals such as hummingbirds, monkeys, and fruit bats can see the colors and are attracted by them. Insects can see ultraviolet colors that the flowers produce, also.
