		- The number of the color pair to retrieve information for.

	      o $f
		- A reference to which to return the foreground color of the color pair. The information returned will be a color number referring
		to one of the pre-defined colors or a color defined previously by ncurses_init_color(3) if the terminal supports color changing.

	      o $b
		- A reference to which to return the background color of the color pair. The information returned will be a color number referring
		to one of the pre-defined colors or a color defined previously by ncurses_init_color(3) if the terminal supports color changing.

ncurses_init_color - Define a terminal color

SYNOPSIS

       int ncurses_init_color (int  $color, int  $r, int  $g, int  $b)

DESCRIPTION

	Defines  or redefines the given color. When this function is called, all occurrences of the given color on the screen, if any, immediately
       change to the new definition.

	Color capabilities must be supported by the terminal and initialized using ncurses_start_color(3) prior to calling this function. In addi-
       tion, the terminal must have color changing capabilities; use ncurses_can_change_color(3) to check for this.

PARAMETERS

	      o $color
		- The identification number of the color to redefine. It may be one of the default color constants.

	      o $r
		- A color value, between 0 and 1000, for the red component.

	      o $g
		- A color value, between 0 and 1000, for the green component.

	      o $b
		- A color value, between 0 and 1000, for the blue component.

RETURN VALUES

	Returns  -1 if the function was successful, and 0 if ncurses or terminal color capabilities have not been initialized or the terminal does
       not have color changing capabilities.
