What did the glove mean on queen elizabeth 1 rainbow portrait?

The Rainbow Portrait of Queen Elizabeth I does not depict the queen wearing a glove. The iconic portrait, painted by an unknown artist around 1592, features Elizabeth I in a lavish, jeweled gown and a richly embroidered ermine robe. Her right hand rests on a globe, symbolizing her dominion over the world, and her left hand holds a white, feathered fan.

It's possible you are thinking of a different portrait of Elizabeth I or misremembering the details of the Rainbow Portrait.
