Now we all understand that when it comes to video games, rules of normalcy can be bent, especially when it comes to character appearances.
It's possible to have female characters with large breasts and they won't fall-over every time they try to stand up, or to have male characters that carry huge swords that are taller than them even if they look like a skinny high school student rather than a muscle-man type.
It's kind of the unspoken rule that people should just go with what's in the game and just pay attention to the story and the rest of the game.
But I've noticed that one particular theme occurs a lot, being hair styles and their colors, and that brings me to the one particular hair color: Silver
Now automatically the idea of silver hair is "cool" to most people. Silver isn't something that can be seen in real life except when you've become old are just really stressed. Silver hair has that appeal to people that it's uncommon and a person with silver hair must be something other than a normal human being to have that kind of hair. And anything not normal or uncommon is considered "cool".
With that thought already in our brains, when we see someone with silver hair, we already deem them someone "cool" within the game.
Perhaps the silver hair has been done just a little too much. Silver-hair has now become more of a stereotype than anything else really. And when you actually analyze most of above characters, they're arguably not as cool in the game story despite their appearances.
I suppose over-all what I'm saying is that utilizing silver-hair isn't bad, but now that almost every game company has at least one character with silver-hair, why not give the natural hair colors some more spotlight, eh?
