In dragonkin form, skin tones range over the entire natural spectrum from the lightest beige to the darkest brown and every shade in between. Some elemental colors like shades of blue, green, red, or white may also be seen.
No color is off-limits for hair.
Sclera is rarely seen due to iris size, and the pupil is slitted as a lizard's would be expected--whether in dragon or humanoid form. The iris is large and can can be any color.
Height ranges wildly from as short as 5'5" to as tall as 7'5", and the dragon form size will determine the humanoid height.
