To configure your screen for 256 colors, include the following your your ~/.screenrc:
#terminfo and termcap for nice 256 color terminal
# allow bold colors - necessary for some reason
attrcolor b ".I"
# tell screen how to set colors. AB = background, AF=foreground
termcapinfo xterm "Co#256:AB=\E[48;5;%dm:AF=\E[38;5;%dm"
termcapinfo xterm-color "Co#256:AB=\E[48;5;%dm:AF=\E[38;5;%dm"
# erase background with current bg color
defbce "on"
term screen-256color
