+  <p>
+    For colors that have a luminance close to the <code>0.55</code> threshold, it can be useful to <strong>override</strong> the <code>findColorInvert()</code> function, and rather set the invert color <strong>manually.</strong>
+    <br>
+    For example, this shade of <span class="bd-color" style="background: hsl(294, 71%, 79%); float: none; height: 16px; width: 16px; margin-right: 0; vertical-align: middle;"></span> purple has a color luminance of <code>0.5529</code>. It can be preferable to set a color invert of white instead of transparent black:
