# Small modifications by jjjordan to better suit white backgrounds and 16-color
# consoles. (Original colors commented out below)
# Standard colors:
#
# Foreground:
# white cyan magenta blue yellow green red black
#
# Background:
# bg_white bg_cyan bg_magenta bg_blue bg_yellow bg_green bg_red bg_black
#
#
# For 16 color and 256 color xterms: "export TERM=xterm-16color", the following
# brighter than normal colors are available ( Note that you need an xterm which
# was compiled to support 16 or 256 colors and a matching termcap/terminfo entry
# for it.)
#
# Foreground:
# WHITE CYAN MAGENTA BLUE YELLOW GREEN RED BLACK
#
# Background:
# bg_WHITE bg_CYAN bg_MAGENTA bg_BLUE bg_YELLOW bg_GREEN bg_RED bg_BLACK
#
#
# For 256 color xterm: "export TERM=xterm-256color", the following become available
# ( Note that you need an xterm which was compiled to support 256 colors and a
# matching termcap/terminfo entry for it. )
#
# fg_RGB and bg_RGB, where R, G, and B range from 0 - 5. So: fg_500 is bright red.
#
# fg_NN and bg_NN give shades of grey, where the intensity, NN, ranges from 0 - 23.
