If I understand what you want correctly, you probably want to use this selector.
如果我正确理解你想要什么，你可能想使用这个选择器。
Original CSS which make the placeholder gray
使占位符变灰的原始 CSS
.select2-default {
color: #f00 !important;
}
Change your preferred placeholder color
更改首选占位符颜色
.select2-default {
color: #f00 !important;
}
Specific placeholder color (using id)
特定的占位符颜色（使用 id）
#s2id_<elementid> .select2-default {
color: #f00 !important;
}
Replace with the original inputor selectid
替换为原始input或selectid
In this case
在这种情况下
#s2id_leadadd_mode_of_enq .select2-default {
color: #f00 !important;
}
Also, another note for placeholder to work, you have to add an empty <option></option>or else the first option will be automatically selected, but not the placeholder.
此外，占位符工作的另一个注意事项，您必须添加一个空的<option></option>，否则将自动选择第一个选项，而不是占位符。
Like so
像这样
<select id="leadadd_mode_of_enq" name="leadadd_mode_of_enq" class="select2 req_place" data-select-search="true" placeholder="Mode of enquiry">
<option></option>
<option value="1">Opt1</option>
<option value="2">Opt2</option>
</select>

select2 copies css classes from source selecttag to it's container. So, you can simply use this css for your html:
select2 将 css 类从源select标记复制到它的容器。因此，您可以简单地将这个 css 用于您的 html：
.select2-container.req_place .select2-default .select2-chosen {
color:#FFF !important;
}
