Quoting from the Healthline website, eggs are available in various colors. Brown and white are usually found in supermarkets. However, many people don’t know what causes eggs to have different colors.
The answer is quite simple, namely the color of the egg depends on the type of chicken. For example, White Leghorn chickens lay eggs with white shells, while Plymouth Rocks and Rhode Island Reds lay eggs with brown shells.
Some types of chickens, such as Araucana, Ameraucana, Dongxiang, and Lushi, even lay blue or turquoise eggs.
The different colors of egg shells come from pigments produced by chickens. The main pigment in brown eggshells is called protoporphyrin IX. It is made from heme, the compound that gives blood its red color.
The main pigment found in blue eggshells is called biliverdin, which also comes from heme. It’s the same pigment that sometimes gives the blue-green color.
Egg shell color can also vary in the same type of chicken, depending on the genetic dominance of each chicken. Although genetics is the main factor that determines egg color, other factors can also influence it.
For example, as chickens that lay brown eggs get older, they tend to produce larger, lighter colored eggs.
The chicken’s environment, diet, and stress level are factors that can make the color lighter or darker but do not necessarily change the color itself. Race is still the main factor in determining egg color.

This means that the color of the egg shell has little effect on its health. The only real difference is the pigment in the shell.
However, there are other factors that can influence the nutritional content of an egg. For example, the chicken’s environment has a big influence. Eggs from chickens left to roam in the sun contain 3–4 times as much vitamin D.
