4.1.63.4 color_resources

The X11 terminal honors the following resources (shown here with their default values) or the greyscale resources. The values may be color names as listed in the X11 rgb.txt file on your system, hexadecimal RGB color specifications (see X11 documentation), or a color name followed by a comma and an `intensity` value from 0 to 1. For example, `blue, 0.5` means a half intensity blue.

      gnuplot*background:  white
      gnuplot*textColor:   black
      gnuplot*borderColor: black
      gnuplot*axisColor:   black
      gnuplot*line1Color:  red
      gnuplot*line2Color:  green
      gnuplot*line3Color:  blue
      gnuplot*line4Color:  magenta
      gnuplot*line5Color:  cyan
      gnuplot*line6Color:  sienna
      gnuplot*line7Color:  orange
      gnuplot*line8Color:  coral
     

The command-line syntax for these is simple only for background, which maps directly to the usual X11 toolkit option "-bg". All others can only be set on the command line by use of the generic "-xrm" resource override option

Examples:

           gnuplot -background coral

to change the background color.

           gnuplot -xrm 'gnuplot*line1Color:blue'

to override the first linetype color.
