为动态生成的div设置不同的颜色

I have a functionality in a page. 1: Edit Language

1: Edit Language

When page loads, In edit language section language div(english, german, french) color need to set randomly.

eg: english - blue, german - red, french - green

If user change the ranking drop-down (1 to 5) change language div color.

At present color is changing in div but that not showing when page loads. Please check my demo and image.

    }, {
        id: "2",
        title_en: "Hindi"
    }, {
        id: "3",
        title_en: "Arabi"
    }

    ]
