Melanism causes Willow's markings and Chymos to be dark in color while retaining its traits. Rules:

• Dark fur and either no markings or all markings are dark and mute in color
  • Manes, hair, eyebrows, etc. may be a darker or lighter color
• Dark Chymos, either off none of the sliders or off the dark end of Earthy Soil
  • Melanistic Willows will keep the same Chymos trait despite the color and will pair with their current traits.
