The dwarf and human models have facial hair which change colour, however the hair around the lips of the 3d models do not change colour.
Also, the colours chosen for hair - at least red, dark brown, and blonde, aren\'t very convincing. The blonde looks greenish, the red looks too artificial, and the brown also doesn\'t look like hair should. It\'s simply a matter of choosing a better colour and plugging those values into the game, no biggy.
This is cool though! It\'s nice to see more variation in the game like this, even though it\'s such a superficial little thing.
