In Ethiopian Orthodox tradition, it is customary to wear black or dark colors to funerals as a sign of mourning. While white may also be acceptable in some contexts, black is generally more appropriate and respectful for such occasions. If you're attending an Ethiopian Orthodox funeral in America, it's best to opt for black to honor the cultural customs.
