In British Courts, a black capnote is the ultimate symbol of doom for a condemned man. Seeing a judge put it on lets all present in the courtroom know that, barring some miraculous appeal or other happenstance, the fate of the prisoner at the dock has been sealed. The sentence of death shall soon be passed. While British Judges are still issued the caps, the death penalty has been abolishednote (and now banned Europe-wide by the European Convention on Human Rights), so they're unlikely to ever see use (with the possible exception of cases where British Law Lords still act as court of final appeal for residual colonies or for former colonies which apply British law and still have the death penalty).
Despite this, a judge wearing a black cap still serves as shorthand for "this prisoner's been sentenced to hang" (similarly to an executioner's hood). A particularly crazy Hanging Judge might even be already wearing it.
The cap has a black Color Motif both because black is the traditional color of death and mourning note , and to signify that the judge is humble before God who has the only real power over life and death.
Useless trivia: when the British ruled over Ireland, the judicial black cap was known in Gaelic as the cai-bais, pronounced "kybosh". Thus a new word entered English. Of course, the judge wasn't so much putting the kybosh on his own head as, symbolically, on the condemned man's...
