# X server format 8-bit-per-component 24-bit int RGB values.

# Here we think in terms of a single
# 24-bit RGB color value, where
# black = 0x000000
# red = 0xFF0000
# green = 0x00FF00
# blue = 0x0000FF
# white = 0xFFFFFF
# This is the usual format for pixels
# in modern X visuals.

# Return a color from x11_color_name::x11_colors table.
# Predefine some colors for convenience:

rgb8_red: Rgb8; # dumps rgb.pkg and reg8.pkg into the same namespace. :-( XXX SUCKO FIXME.
