RmR = Merle Roan, nR/RR = Roan

Overview:

• Lightens the body, leaving the head and legs alone.
• Edges should be clearly blended, often most sharp when reaching maximum.
• Ranges in the amount of lightening, from subtle to near-white depending on base.
• Optional features:
  • May show "corn spots", small spots/nicks in the roan that expose the base color beneath.
  • May show "reverse dappling", dapples that are darker than what's below them.
• Mane/Tail: May have light blending at the roots.
• Skin: No effect
• Eyes: No effect

Interactions:

• Blotted: Blotted may affect Roan.
• Dun: Roan may lighten the presentation of Dun but not fully mask the primitive markings.
• Sooty: Sooty may darken Roan slightly but not fully mask it; lightening must still be obvious.

Range:

• Minimum: Should clearly originate from the top of the butt and blend outward. Visible lightening at least to the withers horizontally. and at least to the belly line vertically.
• Maximum: Lightening up to the edge of the jaw/ears, and just above the knees/hocks.
