Estela has a striking grulla (mouse-gray) coat, characterized by a grayish body with darker points. Its mane and tail are dark, nearly black, which contrasts with the lighter body color. When in motion, she demonstrates a well-proportioned and athletic physique, and has a sleek build with defined muscles, particularly in the legs and shoulders. Overall her appearance is that of a young, vigorous horse with a balanced and elegant structure with good health and agility.
