There are no such guidelines for generating colorPrimaryDark. It just has to be a darker shade to the primary color. Here is the code for generating a darker shade of a given color

public static int manipulateColor(int color, float factor) {
    int a = Color.alpha(color);
    int r = Math.round(Color.red(color) * factor);
    int g = Math.round(Color.green(color) * factor);
    int b = Math.round(Color.blue(color) * factor);
    return Color.argb(a,
            Math.min(r,255),
            Math.min(g,255),
            Math.min(b,255));
}

factor represents how much you want to darken it, pass anything between 0-1

You can change color of status bar as:- 

if (android.os.Build.VERSION.SDK_INT >= 21)                                               
            {
                getWindow().setStatusBarColor(getResources().getColor(R.color.anycolor));              

            }
