Moriarty the Patriot analysis...
It has been a while since I though about this theory, so I am making a post out of it.
My theory is simple : every mtp characters with an unnatural eye color is metaphorical.
By this I mean that the colors used for their eyes is here to comunicate something.
My though is : William and Louis eye color, crimson red, means, based on research I did, "the fire keeper" -> the one who carries burning violence in itself.
As some members of the fandom might have noticed, Louis eye color isnt quite clear in the manga, as it kept changing, balancing between a shade of red and purple. Apparently this shade means accomplishement in your True self. As to find your place in the world by creating your own. This might be the message behind his iris' shade evolution.
William, otherwise, kept this bright red shade for a longtime, burning anger I suppose.
Remember in the Final Problem, William Iris turned darker, deep crimson red. Its eyes losed their light, they became cloudy, heavy, as if any color was unbearable to carry, just like any meaning disappeared from his acts and the last thing consuming him was the weight of guilt.
Post final problem William, in the second part, starts to re-gain its old shade but recently we've been witnessing new changes concerning his gaze. It cooled down and his spark is redussing. Are we getting a new angsty arc ?
Did I forgot someone ? Could that be Charles Augustus Milverton ?
Amber iris, snake-like pupils. The embodiement of the snake from Eden. What is that supposed to mean ? Excellent conversationalist, attention keeper.
I tend to believe, as how evil Milverton is potrayed, we should not forget that his character is here to unveil the truth. As he is raised as a arrogant bully. There's a deeper meaning behind his eye shape and smile.
To me, Milverton embodies the fear of being seen as who we truely are, with our rotten side. Being seen as vulnerable once revealed naked to a sharp-teeth crowd.
