    int red = (int) ((Color.red(color) * (1 - factor) / 255 + factor) * 255);
    int green = (int) ((Color.green(color) * (1 - factor) / 255 + factor) * 255);
    int blue = (int) ((Color.blue(color) * (1 - factor) / 255 + factor) * 255);
    return Color.argb(Color.alpha(color), red, green, blue);
}
