What happens to the egg when heated?
Denaturation is what happens when heat is applied to the eggs. The heat coming from your stove denatures the protein by disrupting some of its bonds that held the molecule into shape. In the case of hard-boiled eggs, the proteins clump together and solidify, causing the egg white and yolk to harden.

What causes egg color?
All eggs start out white in color; those that are laid in shades other than white have pigments deposited on them as the eggs travel through the hen’s oviduct. Chickens that lay brown tinted eggs deposit the pigment protoporphyrin on the eggs late in the process of forming the shell.
