AS3 - 为图像添加棕褐色效果

Question

如何为图像添加棕褐色（深棕色 - 灰色）色彩效果？可以通过以下功能完成吗？

import fl.motion.AdjustColor;
import flash.filters.ColorMatrixFilter;
//
var colorFilter:AdjustColor = new AdjustColor();
var mColorMatrix:ColorMatrixFilter;
var mMatrix:Array = [];

function adjustColors(e:Event=null):void{

    colorFilter.brightness = 10
    colorFilter.contrast =  20
    colorFilter.saturation =  40
    colorFilter.hue =  30

    mMatrix = colorFilter.CalculateFinalFlatArray();
    mColorMatrix = new ColorMatrixFilter(mMatrix);
 //

    mymc.filters = [mColorMatrix];

}
