Gambit said the only equilibrium was mixed, with 1⁄5 each of (blue sword, blue armor), (blue sword, green armor), (yellow sword, yellow armor), (green sword, yellow armor), and (green sword, green armor).
FWIW, my calculations confirm this—you beat me to posting. One nitpick—this is not the only equilibrium, you can transfer weight from (blue, green) to (red, green) up to 10%.
