Manderbolt smooth color. Use LOG2 as Math.log(2); Use converged Z absolute

manderbolt.smoothcolor.java

public Color getFractalColor(FractalPointData fractalPointData){
        double mu = fractalPointData.getIterations() + 1 - Math.log(Math.log(fractalPointData.getConvergedAbsolute()/LOG2)/LOG2);

        int red = (int)(Math.sin(redFrequency * mu + redChannelPhase) * 128f + 127f);
        int green = (int)(Math.sin(greenFrequency * mu + greenChannelPhase) * 128f + 127f);
        int blue = (int)(Math.sin(blueFrequency * mu + blueChannelPhase) * 128f + 127f);

        red = Utils.Clamp(red, 0, 255);
        green = Utils.Clamp(green, 0, 255);
        blue = Utils.Clamp(blue, 0 , 255);

        return new Color(red, green, blue);
   }
