So the gene for e.g. blue eye colour codes for the amino acid sequence that forms a blue pigment. The gene for sickle cell anaemia has a mutation that changes the shape of haemoglobin.
How are attibrutes such as the shape of facial features, predisposition to balding or mental health issues etc. genetically inherited? Do they all really happen because of different proteins?

Bonus fact: there’s no blue pigment in blue eyes; it’s brown pigment but the structure of the iris causes Tyndall scattering that makes them appear blue (similar to the Rayleigh scattering that makes our sky appear blue).
