	)

----------------------------------------------------------------generalColor-

Sets the current color to the desired color specified by the red, green and blue values.

Parameters:

	color	Holds the color.
	red	The red component of the color.
	green	The green component of the color.
	blue	The blue component of the color.

void gray	(	RGBAColor *	color,
		unsigned char	intensity
	)
