title: css filter to make elements one color
body: <p>The following CSS filter:</p>
  
  <pre><code>filter: brightness(0) invert(1);
  </code></pre>
  
  <p>makes elements all-white (<a href="https://stackoverflow.com/questions/24224112/css-filter-make-color-image-with-transparency-white">source</a>). Neat, but is there a way to make them another color instead, e.g. blue? This is for situations where there is a transparent background, e.g. an icon. I want to make the icon one arbitrary color.</p>
