- Grulla or grullo, also called blue dun, gray dun or mouse dun, is a color of horses in the dun family, characterized by tan-gray or mouse-colored hairs on the body, often with shoulder and dorsal stripes and black barring on the lower legs. In this coloration, each individual hair is mouse-colored, unlike a roan, which is composed of a mixture of dark and light hairs. The several shades of grulla are informally referred to with a variety of terms, including black dun, blue dun, slate grulla, silver grulla or light grulla, silver dun, or lobo dun. Silver grulla may also refer to a grullo horse with silver dapple, regardless of shade. In the Icelandic horse, the grulla color is called gray dun, in the Highland pony it is called mouse dun, and in the Norwegian Fjord horse, grå or gråblakk (literally, "gray dun"). The word "grulla" in Spanish means crane. Because of the origin of the name, some people will refer to a mare as a grulla and a stallion or gelding as a grullo, pronounced /ˈɡrjuːjə/ GREW-yə and /ˈɡrjuːjoʊ/ GREW-yoh. (The original Spanish noun is pronounced [ˈɡɾuʝa] in American Spanish and [ˈɡɾuʎa] in Peninsular Spanish.) In terms of equine coat color genetics, all of these shades are based on the dun gene acting as a dilution gene over the black gene. Because the grulla color is not due to the gray gene, a grulla horse remains the same basic color from birth, though some minor shade variation may occur from summer to winter coats. If a grulla also carries the gray gene, it will be born a mouse tan-gray shade, usually with bold primitive markings, but then lighten and eventually develop a white hair coat with age. Because black is less common in general than bay or chestnut, grulla is likewise less common than red duns or bay (classic or zebra) duns. For example, only 0.7% of quarter horses registered each year with the AQHA are grulla. The most obvious ways to tell whether a horse is grulla are not only the gray or tan-gray body color, but also its primitive markings, which include some or all of the following: dark face, cobwebbing around the eyes and forehead, dark mottling on the body, leg barring (sometimes called tiger striping), dark ear tips and edging, dark ear barring, dark shadowing of the neck, dark dorsal and transverse striping, and light guard hairs bordering a dark mane and tail.

- Souris est, dans le domaine de l'hippologie, une couleur de robe du cheval, assez rare. Le pelage est dans les tons gris. La crinière, la queue, le contour des oreilles et le bas des membres sont noirs. Ces chevaux présentent aussi des marques primitives, raie de mulet, zébrures sur les membres et crins bicolores. La peau est sombre. Ils portent rarement des marques blanches. L'hypothèse de l'action d'un gène dominant est formulée par des chercheurs américains dès 1939 et 1948, cette hypothèse étant confirmée par le chercheur islandais Stefán Aðalsteinsson en 1978. La robe souris est génétiquement due au gène de dilution nommé Dun (D), agissant sur une robe de base noire pour l'éclaircir en gris, d'où la terminologie génétique de noir dun. Cette robe était probablement fréquente chez les ancêtres des chevaux domestiques actuels ; les chevaux de robe souris se trouvent principalement chez des races de type primitif, telles que le Konik et le Sorraia. Les allèles du gène Dun étant additifs avec ceux des gènes Crème, Champagne, et les formes de robes pie, la robe souris peut se combiner à d'autres dilutions et à des panachures. (fr)
