Modify the hue of a background image in PNG format

I'm currently using a CSS selector on my site to display an icon for external links on any href that isn't directing to my own domain. Here's the code snippet I'm referring to:

a[class=" external-link"]::after {
    content: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAoAAAAKCAYAAACNMs+9AAAAQElEQVR42qXKwQkAIAxDUUdxtO6/RBQkQZvSi8I/pL4BoGw/XPkh4XigPmsUgh0626AjRsgxHTkUThsG2T/sIlzdTsp52kSS1wAAAABJRU5ErkJggg==);
    position: relative;
    top: -3px;
    margin: 0 3px 0 5px;
}

The image displayed is grey, while the rest of the link has a color of #0273d4. I was wondering if it's possible to change the color of the image only, without affecting the background text of the href?

Answer №1

One great option to customize icons as if they were text is by using Font Awesome.

.blue {
  color: #0273d4
}

.red {
  color: red
}

.green {
  color: green
}
<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.8.1/css/all.css" integrity="sha384-50oBUHEmvpQ+1lW4y57PTFmhCaXp0ML5d60M1M7uH2+nqUivzIebhndOJK28anvf" crossorigin="anonymous">

<ul>
  <li><a class="blue" href="#">External Link <i class="fas fa-external-link-alt"></i></a></li>
  <li><a class="red" href="#">External Link <i class="fas fa-external-link-alt"></i></a></li>
  <li><a class="green" href="#">External Link <i class="fas fa-external-link-alt"></i></a></li>
</ul>

Alternatively, you can utilize the filter property as suggested by Temani Afif. Check out His Link for more information. Further Reading
