I get that coat colours (looks) give more uniqueness etc.
But then we are again talking about what a individual wants/expects, and not what's in the game and meant by Frontier.
For me, character traits are equally important.
It's only logical that most people expect colour variation,because it is the biggest visual uniqueness factor - that's a fact nobody can deny.
It is also way easier to depict something visually in a game,instead of personality/character traits,which are not literally visible with the bare eyes/at first sight,but require studying of that particular individual.Not to mention that procedurally generated colours/markings/patterns would add a huge boost to the genetics part of the game and the overall replayability.People still can't tell if the different personalities are ingame,because the animals all seem to act randomly - but that's not the topic of this thread.
The topic is also not based on solely peoples' expectations,because Frontier advertised with colour variations and unique markings/patterns and people are now wondering what happened with those features.In addition there is the fact of the dev post at the end of the beta,which said that these features were just turned off for the beta,but will be there at full release,which turned out to be not true.
