Wow..I can't believe it! I think I had an really inspired idea with this thread!
Anyways...yeah...I think each anime series (not character) has it's own color.
To me:
- Fate/Stay Night = purple
- Ouran High School Host Club = pink
- Tenjou Thengi = blue
- Naruto = Black
- Inuyasha = brown
- Chobits = white
- Jigoku Shoujo = Red
- NANA = green
- Sailor Moon = Yellow
- Shuffle! = orange
- Elfen Lied = gold
etc.
These are my favorites anime series and the colors I think suits them....How abou you? :D
