DIVIDER-COLOR (numeric)

This special property sets the color of the dividers for the grid. Set this to the color number of the desired color (such as 1 for black or 9 for dark gray). The color ignores the grid's foreground and background intensity — it is treated as the final color value. When this property is set to zero (the default), a system-specific divider color is used. This color depends on the background color for the grid.
