我想在下面的复选框（名称是流派）中将选中标记（勾号）颜色更改为蓝色。但它显示为黑色。

I want to change the checked-mark (tick) color in the following checkbox (its name is "genres") as "blue". But it is displayed as "black".

<input type="checkbox" name="genres" value="adventure" id="adventure_id">

       width: 1.2ex;
       height: 0.4ex;
       background: rgba(0, 0, 0, 0);
       top: 0.9ex;
       left: 0.4ex;
       border: 3px solid blue;
       border-top: none;
       border-right: none;
       -webkit-transform: rotate(-45deg);
       -moz-transform: rotate(-45deg);
       -o-transform: rotate(-45deg);
       -ms-transform: rotate(-45deg);
       transform: rotate(-45deg);
    }

    input[type="checkbox"] {
       line-height: 2.1ex;
    }

    input[type="radio"],
    input[type="checkbox"] {
        position: absolute;
        left: -999em;
    }

    input[type="checkbox"] + label {
        position: relative;
        overflow: hidden;
        cursor: pointer;
    }

    input[type="checkbox"] + label::before {
