1. Hue/hue--the color of the object passing
ColorMatrix huematrix=new Colormtrix ();
Huematrix.setrotate (0,hue);
Huematrix.setrotate (1,hue);
Huematrix.setrotate (2.hue);
2. Saturation-the purity of the color, from (0) to 100% saturation to describe
ColorMatrix saturationmatrix=new ColorMatrix ();
Saturationmatrix.setsaturation (saturation);
3. Brightness/lightness--the degree of light and shade relative to the color
ColorMatrix lummatrix=new ColorMatrix ();
Lummatrix.setscale (lum,lum,lun,1);
