GMT Themes

GMT offers 3 built-in themes (classic, modern, and minimal). Classic theme is the default for classic mode and modern theme is the default for modern mode. You can also create and use your own themes by compiling files of desired settings and placing them in your GMT user themes directory (usually ~/.gmt/themes) and naming them theme.conf, where theme is any valid string. The GMT_THEME parameter is used to set the current theme. The table below lists the default settings for the classic, modern, and minimal themes.
