我正在开发使用vintageJS 在线为图像添加效果的网站。我有以下效果

   effect1 = {
        vignette: 0.7,
        viewFinder: "js/ImageEffects/assets/viewfinder/ttv-1.jpg",
        screen: { r: 227, g: 12, b: 169, a: 0.15 }
    };

而且我还有vintageJS的四个基本效果（我从vintageJS的网站获得了四个效果。该网站应该有九个效果，这意味着我需要另外四个效果。我尝试写一些随机值但我没有得到一个好的效果。谁能给出一些产生好的效果的值？
