Why flamingos are pink?

PINK COLOR BEHIND FLAMINGOS:

Flamingos are wading bird normally looks in pink or orange color. They are usually grey or white colored at the time of emerging or hatching. Later they turn into pink color because they eat shrimps and algae. Usually the shrimps and algae contain carotenoids. Carotenoids are reddish brown color. When the flamingos eat algae, the liver extracts these colored pigments. These colored pigments are then absorbed by fats. The fats, then pass into flamingos growing feathers which eventually turns flamingos pink in color. But, when humans eat carotenoids such as carrot and mango, it may not change our color.
