-G
Select color or pattern for filling the underlying box [Default is no fill]. (See SPECIFYING FILL below).
-W
Set pen attributes for the outline of the box [Default is no outline]. (See SPECIFYING PENS below).
pen
The attributes of lines and symbol outlines as defined by pen is a comma delimetered list of width, color and texture, each of which is optional. width can be indicated as a measure (points, centimeters, inches) or as faint, thin[ner|nest], thick[er|est], fat[ter|test], or obese. color specifies a gray shade or color (see SPECIFYING COLOR below). texture is a combination of dashes `-' and dots `.'.
fill
The attribute fill specifies the solid shade or solid color (see SPECIFYING COLOR below) or the pattern used for filling polygons. Patterns are specified as pdpi/pattern, where pattern gives the number of the built-in pattern (1-90) or the name of a Sun 1-, 8-, or 24-bit raster file. The dpi sets the resolution of the image. For 1-bit rasters: use Pdpi/pattern for inverse video, or append :Fcolor[B[color]] to specify fore- and background colors (use color = - for transparency). See GMT Cookbook & Technical Reference Appendix E for information on individual patterns.
color
The color of lines, areas and patterns can be specified by a valid color name; by a gray shade (in the range 0-255); by a decimal color code (r/g/b, each in range 0-255; h-s-v, ranges 0-360, 0-1, 0-1; or c/m/y/k, each in range 0-1); or by a hexadecimal color code (#rrggbb, as used in HTML). See the gmtcolors manpage for more information and a full list of color names.
