If horizontal is FALSE, the colors are groupedin columns instead. The default color palette of Gtk.ColorChooserWidget has27 colors, organized in columns of 3 colors. The default graypalette has 9 grays in a single row. The layout of the color chooser widget works best when thepalettes have 9-10 columns.
