According to the MFHS roster there are 10 hunts with “confederate” in the description of their hunt colors. Mostly “confederate grey”,but at least one “confederate blue” and “confederate cavalry yellow”. 6 in VA, 2 in GA, 1 in MD, 1 in FL.
Yes, the confederacy ended 150 years ago. But all but 2 of these hunt (1899 and 1910) were founded, and defined their colors, in the second half of the 20th century. It IS intentional confederate symbology,at least by the hunt founders, even if not endorsed by current members.
