Who are you to tell someone they cannot make a blue purple-eyed Imperial? It's not your game, you'll never have to look at it. Skyrim is a single player game, someone's blue purple-eyed Imperial will never have the chance to offend your delicate aesthetic sensibilities. It's none of your (or my) business what color hair someone else puts on their character.
Uhh...really making a stretch on that one huh? It has nothing to do with my aesthetic tastes. It is about lore. Imperials are not blue. It just wouldn't make sense. Why would I care what someone does with there own game? However if the blueness was restricted to the PC(player char) only, then that's fine. There should not be blue imperials running around in Tamriel though as NPCs. Strictly speaking lore wise, neither should the PC be doing so either. But again I can just make my PC not blue so why would I care if the option to be blue is there? However the skin color like that would make racial aesthetics mostly meaningless in men. The races need to be more identifiable IMO. But again so long as certain features of the character creation are restricted to the PC I really would not care.
On topic. It really would be great to have a little class name and then a description of that class or a backstory for your character you can see ingame in certain areas like in menu or maybe even on a plaque somewhere after you do something.
