Right now, the symbol and color used to represent an item are determined only by it's type. All items of the same type are represented with the same symbol and color. I think it would be better if items of the same type could be different colors. Also, "artifact" shouldn't be an item type which is immediately recognizable by it's symbol. There should be artifacts that fit into the other item categories. For example, the "Potion of Life" and "Potion of Death" are potions and should be represented by the potion symbol '!'. Ideally, we would not have a special symbol for representing artifacts at all.
