EQUERRY.COM - Fun Barn - What the origin of...? A horse of a different color
Something of a different nature from that under consideration. It was used by Shakespeare as "a horse of the same color" in the Twelfth Night. Legend states that the phrase "a horse of another color" came from the White Horse of Berkshire, a huge carved picture in West Berkshire, almost 400 feet long - covering approximately 2 acres in commemoration of King Ethelrod and his brother Alfred the Great win over the Danes in 871, though the picture is believed to be even older. It was the custom of neighborhood people to make it a "horse of another color" periodically by clearing out the grass and debris from the trenches by which the figure is outlined.
