Colour Coding

"No! My armour is black because I’m poor. I’m not evil, I just can’t afford to polish i-"
- Last words of Bern the Black Knight

Clothing is important. What you were, what you look like, how you dress - it all tells people things, even if just at an unconscious level.

CAUTION: APPLYING THE FOLLOWING STANDARDS TO REAL LIFE COULD BE HAZARDOUS TO YOUR HEALTH.

Clothing

Bath Robe = Gelhallee.
Black Clothing = Evil. End of story.
Brown Clothing = Trustworthy
Drab Clothing = Someone boring, in hiding or, perhaps, a killer in disguise.
Bright Colours = Good.
Green Clothing = Bard, Cleric Druid, Healer
Loin Cloth = Barbarian, of course. Especially if it's cold and they're not wearing much else.
Loin Cloth Over Their Pants = Super hero in wrong setting.
Red = It’s the colour of blood. What do you think?
Robes = Wizard (or confused cross-dresser)
Very Bright Colours = Unreliable.

Eyes

Blue = Good.
Black = Evil.
Brown = Boldness/Humour. (Not necessarily good.)
Gold = Someone with an interesting life.
Green = Uses magic.
Grey = Healer.
Hazel = Nice. (But for some reason, hazel eyes tend to be rare.)
Red = Evil.
Silver = Enchanter.
Violet = Royal Birth.
White = Wisdom.

Hair

Black = Evil.
Blond = Good.
Brown = Generally nice.
Red = Uses magic.
White = Interesting life or wise

No hair generally means foreign, or very old, or evil fellow hiding his black hair. If the latter, s/he may have invented contacts to hide their evil eyes as well.

Skin Complexion:

Black = Evil. (But you figured that one out already, right?)
Corpse-white Complexion = Ditto.
Grey = Undead. (That means evil.) Or wizard who has spent too much time in libraries. (Generally evil, too.)
Tan/Brown = Good.
