html - 如何创建具有不同圆环颜色的有序列表

Question

我正在使用有序列表显示结果。现在我想在数字中添加一个圆圈，颜色从绿色变为红色。使用是第一个结果是优先级，其他的次之。所以颜色渐变从绿色变为红色。

.listAddress li {
    padding-top: 15px;
    padding-bottom: 15px;
    display: list-item;
    padding: 10px 10px;
    color: #252424;
    font-size: 12px;
     width: auto;
    font-style: normal;
    text-transform: uppercase;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;

<ol class="listAddress">
<li>365 W Northwest Hwy, Palatine, IL 60067, USA</li>
<li>365 W Northwest Hwy, Palatine, IL 60067, USA</li>
<li>365 W Northwest Hwy, Palatine, IL 60067, USA</li>
</ol>
