如何更改所选选项文本的颜色？

Question

I have created an HTML form using bootstrap and some CSS. I have a select box. When a user selects an option it needs to change the color to white. Currently, the text color is Black. I need to change it to White. I tried most of the things but nothing worked.

Here is the code,

<div class="wrap-input1001 validate-input">
     <select name="accType" class="form-control" placeholder="Choose One Thing">
             <option></option>
             <option value="RD">RD</option>
             <option value="BS">BS</option>
             <option value="TW">TW</option>
             <option value="AP">AP</option>
      </select>
 </div>

Here is the image,

CSS Code,

.select2-container--bootstrap4 .select2-selection--single{height:calc(2.25rem + 2px)!important}.select2-container--bootstrap4 .select2-selection--single .select2-selection__placeholder{color:#CBB0FC;line-height:2.25rem}.select2-container--bootstrap4 .select2-selection--single .select2-selection__arrow{position:absolute;top:50%;right:3px;width:20px}.select2-container--bootstrap4 .select2-selection--single .select2-selection__arrow b{top:60%;border-color:#fff transparent transparent;border-style:solid;border-width:5px 4px 0;width:0;height:0;left:50%;margin-left:-4px;margin-top:-2px;position:absolute}.select2-container--bootstrap4 .select2-selection--single .select2-selection__rendered{line-height:2.25rem}.select2-search--dropdown .select2-search__field{border:1px solid #ced4da;border-radius:.25rem}.select2-results__message{color:#6c757d}.select2-container--bootstrap4 .select2-selection--multiple{min-height:calc(2.25rem + 2px)!important}.select2-container--bootstrap4 .select2-selection--multiple .select2-selection__rendered{-webkit-box-sizing:border-box;box-sizing:border-box;list-style:none;margin:0;padding:0 5px;width:100%}.select2-container--bootstrap4 .select2-selection--multiple .select2-selection__choice{color:#343a40;border:1px solid #bdc6d0;border-radius:.2rem;padding:0 5px 0 0;cursor:pointer;float:left;margin-top:.3em;margin-right:5px}.select2-container--bootstrap4 .select2-selection--multiple .select2-selection__choice__remove{color:#bdc6d0;font-weight:700;margin-left:3px;margin-right:1px;padding-right:3px;padding-left:3px;float:left}.select2-container--bootstrap4 .select2-selection--multiple .select2-selection__choice__remove:hover{color:#343a40}.select2-container :focus{outline:0}.select2-container--bootstrap4 .select2-selection{border:1px solid #ced4da;border-radius:.25rem;width:100%}.select2-container--bootstrap4.select2-container--focus .select2-selection{border-color:#17a2b8;-webkit-box-shadow:0 0 0 .2rem rgba(0,123,255,.25);box-shadow:0 0 0 .2rem rgba(0,123,255,.25)}.select2-container--bootstrap4.select2-container--focus.select2-container--open .select2-selection{border-bottom:none;border-bottom-left-radius:0;border-bottom-right-radius:0}select.is-invalid~.select2-container--bootstrap4 .select2-selection{border-color:#dc3545}select.is-valid~.select2-container--bootstrap4 .select2-selection{border-color:#28a745}.select2-container--bootstrap4 .select2-dropdown{border-color:#ced4da;border-top:none;border-top-left-radius:0;border-top-right-radius:0}.select2-container--bootstrap4 .select2-dropdown .select2-results__option[aria-selected=true]{background-color:#e9ecef;}.select2-container--bootstrap4 .select2-results__option--highlighted,.select2-container--bootstrap4 .select2-results__option--highlighted.select2-results__option[aria-selected=true]{background-color:#007bff;color:#f8f9fa}.select2-container--bootstrap4 .select2-results__option[role=group]{padding:0}.select2-container--bootstrap4 .select2-results__options{max-height:15em;overflow-y:auto}.select2-container--bootstrap4 .select2-results__group{padding:6px;display:list-item;color:#6c757d}.select2-container--bootstrap4 .select2-selection__clear{width:1.2em;height:1.2em;line-height:1.15em;padding-left:.3em;margin-top:.5em;border-radius:100%;background-color:#6c757d;color:#f8f9fa;float:right;margin-right:.3em}.select2-container--bootstrap4 .select2-selection__clear:hover{background-color:#343a40}

Answer 1

You need to add code something like this:

 .select2-container--default .select2-selection--single .select2-selection__rendered { color: #FFF; }
