Grey pants

Rejecting the offer of some new pants, Stephen tells Mulligan, "I can't wear them if they are grey." He is rigidly upholding an outdated Victorian convention, no doubt because of the terrible guilt that he feels about his mother's death. Symbolically, his somber black clothes also make him a type of Hamlet, rejecting his world's expectations of him.
