The jester hat is a silly hat with bells on worn by performers in the Tudor period and beyond.
Red and Green should never be seen, except on fools is a reference to a colour clash and peoples fashion sense.
I always like to think this phrase comes from the colours worn by medieval court jesters, but that probably not true, the phrase could come from the running lights on ships, which have traditionally been red on one side and green on the other. If another vessel saw green or red lights ahead in the dark, it would mean they were on a collision course.
This is comercial hat found in job lot of hats I got off ebay used by a local theatre group.
Where does a werewolf go when he loses his tail?
