All programs using color can use a color definition file called COLOR.DEF. The file can be located in the current working directory or in DAT. Programs will first look in the working directory, then in DAT. If no COLOR.DEF file is given, default is used. Be careful with color setting, unexpected results might occur, like getting a blank screen when plotting white traces on a white background. Several color settings are universal like setting colors for titles, however several color settings are specific for particular programs, see example file below. Since colors can also be used for the Postscript file, there is an option for using color on the screen but not for Postscript, since it is more likely that the user will have a color screen than a color Postscript plotter. Sending a color plot file to a black and white laser printer results in a plot with gray tones.
The COLOR.DEF file:
This file is for defining SEISAN color objects and for setting the size(of full screen) of the graphics window for individual programs. If no file available, default colors, as given at end of line below, will be used. The entries can come in any order, however the keyword MUST appear as shown below. If an object color is not defined, it will retain its default value. If a black or white background and no colors are chosen, all colors will be reset accordingly.

Since verison 9.0, the size of the window (% of full screen) for most graphics programs is also set in this file.
