Using Bootstrap's CSS classes, is it possible to modify the background color of a table cell?

I'm currently working with Bootstrap 5.0 CSS and attempting to create a table with customized cell colors using some of my own CSS styles. The color property seems to be working correctly, but I'm running into an issue with Bootstrap not recognizing the background property when I try to change the background color. Is there a solution to this problem?

Here is a snippet of my code:

td.colorfy {
    background: blue;
    color: white;
  }
<link href="https://cdn.jsdelivr.net/npm/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="45272a2a31363137243505706b756b75682720312477">[email protected]</a>/dist/css/bootstrap.min.css" rel="stylesheet"/>

<table class="table table-bordered">
  <tr>
    <td class="colorfy">cell</td>
    <td>cell</td>
    <td>cell</td>
  </tr>
</table>

Override any existing bootstrap behavior by simply using the !important directive. Check out more details here.

td.colorfy {
    background: blue !important;
    color: white;
  }
<link href="https://cdn.jsdelivr.net/npm/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="680a07071c1b1c1a0918285d46584658450a0d1c095a">[email protected]</a>/dist/css/bootstrap.min.css" rel="stylesheet"/>

<table class="table table-bordered">
  <tr>
    <td class="colorfy">cell</td>
    <td>cell</td>
    <td>cell</td>
  </tr>
</table>

For a more specific CSS rule:

.table td.colorfy {
    background: blue;
    color: white;
  }
<link href="https://cdn.jsdelivr.net/npm/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="96f4f9f9e2e5e2e4f7e6d6a3b8a6b8a6bbf4f3e2f7a4">[email protected]</a>/dist/css/bootstrap.min.css" rel="stylesheet"/>

<table class="table table-bordered">
  <tr>
    <td class="colorfy">cell</td>
    <td>cell</td>
    <td>cell</td>
  </tr>
</table>

By being more specific like bootstrap or using !important, you can change the background color successfully. The specificity in bootstrap CSS defines the color as:

.table>:not(caption)>*>* {
    padding: .5rem .5rem;
    background-color: var(--bs-table-bg);
    border-bottom-width: 1px;
    box-shadow: inset 0 0 0 9999px var(--bs-table-accent-bg)
}

Therefore, with increased specificity or the use of !important, you can achieve the desired background color.
