Duotone Icons

If you're looking to add multiple colors or tones or swap the layer opacity of your icons, you've come to the right place. Who doesn't love a winning flavor combination?

Our duotone icons (in both the Duotone and Sharp Duotone styles) work just like all of our other icons but with two distinct shades of color. Duotone is a great effect when you're looking to add more of your brand or an illustrative quality to the icons in your project.

Basic Use

Duotone and Sharp Duotone icons use the same syntax Font Awesome icons, and you can reference them like any other icon. They will inherit whatever color is around them, with the secondary layer being a transparent version of the primary color.

<div class="fa-3x">
  <i class="fa-duotone fa-solid fa-camera"></i>
  <!-- a solid duotone camera icon -->
  <i class="fa-duotone fa-solid fa-fire-alt"></i>
  <!-- a solid duotone fire-alt icon -->
  <i class="fa-sharp-duotone fa-solid fa-bus-alt"></i>
  <!-- a solid sharp-duotone bus-alt icon -->
  <i class="fa-sharp-duotone fa-solid fa-fill-drip"></i>
  <!-- a solid sharp-duotone fill-drip icon -->
</div>

Swapping Layer Opacity

You can swap the default opacity of each duotone icon's layers. This will make an icon's primary layer have the default opacity of 40% rather than its secondary layer.

<div class="fa-3x">
  <i class="fa-duotone fa-solid fa-camera"></i>
  <!-- a duotone solid camera icon -->
  <i class="fa-duotone fa-camera fa-swap-opacity"></i>
  <!-- a duotone solid camera icon with swapped opacity -->

  <i class="fa-duotone fa-solid fa-fire-alt"></i>
  <!-- a duotone solid fire-alt icon -->
  <i class="fa-duotone fa-solid fa-fire-alt fa-swap-opacity"></i>
  <!-- a duotone solid fire-alt icon with swapped opacity -->

  <i class="fa-sharp-duotone fa-solid fa-bus-alt"></i>
  <!-- a sharp duotone solid bus-alt icon -->
  <i class="fa-sharp-duotone fa-solid fa-bus-alt fa-swap-opacity"></i>
  <!-- a sharp duotone solid bus-alt icon with swapped opacity -->
</div>

Changing Opacity

By default, the secondary layer in a duotone icon is set to 40% opacity (via an opacity 0.4; rule in Font Awesome's support CSS). You can explicitly set the opacity of a duotone icon's layer by using the CSS custom properties below. New to custom properties? Here are some recommendations on using them in a project.

<div class="fa-3x">
  <i class="fa-duotone fa-solid fa-bus-alt" style="--fa-secondary-opacity: 0.20"></i>
  <!--  secondary layer's opacity set to 20% -->
  <i class="fa-duotone fa-solid fa-bus-alt" style="--fa-secondary-opacity: 0.40"></i>
  <!--  secondary layer's opacity set to 40% -->
  <i class="fa-duotone fa-solid fa-bus-alt" style="--fa-secondary-opacity: 0.60"></i>
  <!--  secondary layer's opacity set to 60% -->
  <i class="fa-duotone fa-solid fa-bus-alt" style="--fa-secondary-opacity: 0.80"></i>
  <!--  secondary layer's opacity set to 80% -->
  <i class="fa-duotone fa-solid fa-bus-alt" style="--fa-secondary-opacity: 1.0"></i>
  <!--  secondary layer's opacity set to 100% -->
</div>

<div class="fa-3x">
  <i class="fa-duotone fa-solid fa-bus-alt" style="--fa-primary-opacity: 0.20"></i>
  <!--  primary layer's opacity set to 20% -->
  <i class="fa-duotone fa-solid fa-bus-alt" style="--fa-primary-opacity: 0.40"></i>
  <!--  primary layer's opacity set to 40% -->
  <i class="fa-duotone fa-solid fa-bus-alt" style="--fa-primary-opacity: 0.60"></i>
  <!--  primary layer's opacity set to 60% -->
  <i class="fa-duotone fa-solid fa-bus-alt" style="--fa-primary-opacity: 0.80"></i>
  <!--  primary layer's opacity set to 80% -->
  <i class="fa-duotone fa-solid fa-bus-alt" style="--fa-primary-opacity: 1.0"></i>
  <!--  primary layer's opacity set to 100% -->
</div>

Coloring Duotone Icons

Like all other Font Awesome icons, duotone icons automatically inherit CSS size and color. A duotone icon consists of a primary and secondary layer. By default, The secondary layer is given an opacity of 40% so that it appears as a lighter shade of the icon's inherited or directly set color.

Using CSS custom properties, we've also added some color hooks to a duotone icon's primary and secondary layers. New to custom properties? Here are some places to set them.

<div class="fa-3x">
  <i class="fa-sharp-duotone fa-solid fa-bus-alt" style="--fa-primary-color: gold;"></i>
  <!-- primary layer color defined -->
  <i class="fa-sharp-duotone fa-solid fa-bus-alt" style="--fa-primary-color: orangered;"></i>
  <!-- primary layer color defined -->
  <i class="fa-sharp-duotone fa-solid fa-fill-drip" style="--fa-secondary-color: limegreen;"></i>
  <!-- secondary layer color defined -->
  <i class="fa-sharp-duotone fa-solid fa-fill-drip" style="--fa-secondary-color: rebeccapurple;"></i>
  <!-- secondary layer color defined -->
  <i
    class="fa-sharp-duotone fa-solid fa-battery-full"
    style="--fa-primary-color: limegreen; --fa-secondary-color: dimgray;"></i>
  <!-- secondary + primary layer color defined -->
  <i
    class="fa-sharp-duotone fa-solid fa-battery-quarter"
    style="--fa-primary-color: orange; --fa-secondary-color: dimgray;"></i>
  <!-- secondary + primary layer color defined -->
</div>

Advanced Use

When you combine all of the coloring, opacity, and other options together, Font Awesome icons get even more awesome. Here are a few ideas on how duotone icons can take your project to the next level.

Use Color to Highlight a Part of an Icon or to Note Status

<div class="fa-3x">
  <i
    class="fa-duotone fa-solid fa-book"
    style="--fa-primary-color: lightseagreen; --fa-secondary-color: linen; --fa-secondary-opacity: 1.0;"></i>
  <i
    class="fa-duotone fa-solid fa-book-spells"
    style="--fa-primary-color: mediumpurple; --fa-secondary-color: linen; --fa-secondary-opacity: 1.0;"></i>
  <i
    class="fa-duotone fa-solid fa-book-medical"
    style="--fa-primary-color: crimson; --fa-secondary-color: linen; --fa-secondary-opacity: 1.0;"></i>
  <i
    class="fa-duotone fa-solid fa-book-user"
    style="--fa-primary-color: peru; --fa-secondary-color: linen; --fa-secondary-opacity: 1.0;"></i>

  <i
    class="fa-duotone fa-solid fa-toggle-off"
    style="--fa-primary-color: silver; --fa-secondary-color: gray; --fa-secondary-opacity: 1.0;"></i>
  <i
    class="fa-duotone fa-solid fa-toggle-on"
    style="--fa-primary-color: dodgerblue; --fa-secondary-color: orange; --fa-secondary-opacity: 1.0;"></i>

  <i
    class="fa-duotone fa-solid fa-file-plus"
    style="--fa-primary-color: white; --fa-secondary-color: limegreen; --fa-secondary-opacity: 1.0;"></i>
  <i
    class="fa-duotone fa-solid fa-file-exclamation"
    style="--fa-primary-color: white; --fa-secondary-color: gold; --fa-secondary-opacity: 1.0;"></i>
  <i
    class="fa-duotone fa-solid fa-file-times"
    style="--fa-primary-color: white; --fa-secondary-color: tomato; --fa-secondary-opacity: 1.0;"></i>
</div>

Create Full-Color Icons that Look Like Illustrations

<div class="fa-3x">
  <i
    class="fa-sharp-duotone fa-solid fa-crow"
    style="--fa-secondary-opacity: 1.0; --fa-primary-color: dodgerblue; --fa-secondary-color: gold;"></i>
  <i
    class="fa-sharp-duotone fa-solid fa-campfire"
    style="--fa-secondary-opacity: 1.0; --fa-primary-color: sienna; --fa-secondary-color: red;"></i>
  <i
    class="fa-sharp-duotone fa-solid fa-birthday-cake"
    style="--fa-secondary-opacity: 1.0; --fa-primary-color: pink; --fa-secondary-color: palevioletred;"></i>
  <i
    class="fa-sharp-duotone fa-solid fa-ear"
    style="--fa-secondary-opacity: 1.0; --fa-primary-color: sandybrown; --fa-secondary-color: bisque;"></i>
  <i

    class="fa-sharp-duotone fa-solid fa-cookie-bite"
    style="--fa-secondary-opacity: 1.0; --fa-primary-color: saddlebrown; --fa-secondary-color: burlywood;"></i>
</div>

Theme Icons with Brand Colors

<style>
  .theme-ravenclaw {
    --fa-secondary-opacity: 1;
    --fa-primary-color: rgb(4, 56, 161);
    --fa-secondary-color: rgb(108, 108, 108);
  }
</style>
<div class="fa-3x">
  <i class="fa-duotone fa-solid fa-hat-wizard theme-ravenclaw"></i>
  <i class="fa-duotone fa-solid fa-flask-potion theme-ravenclaw"></i>

</div>

Using in a Project

CSS custom properties are still a pretty new thing for most folks. We've documented some of the ways you can define them within your project.

Accessibility Best Practices

Because duotone icons are made up of two layers with different color values, they can be more like illustrations than other Font Awesome styles and need extra care for accessibility.

Since they are more complex visually, duotone icons may be harder to read at smaller sizes. In addition to that, the colors and opacity you choose for each icon's layers can also affect their legibility. Some tips for improving legibility and accessibility:

• Render duotone style icons at larger sizes (2x your base type size is a good starting point).
• Test layer colors together to make sure they have enough color contrast.
• Test layer colors together to make sure they handle color-blindness scenarios well.

Custom Icon Uploads Are Like Onions

They now have layers! You can add your very own duotone creations to a Kit if you have a Pro-level plan. Get up to speed on how best to make some, and how to use them once they're in your Kit.

Duotone Classes

Customization

We've added CSS custom properties to make customizing easier and more efficient. Define your own values for the following properties to override and customize Font Awesome's defaults.

Troubleshooting

Can I use Duotone Icons by using CSS pseudo-elements?

Yes, duotone icons can be added to your web projects as CSS pseudo-elements. Doing so is even more complicated than the base difficulty of rendering icons with CSS pseudo-elements though. It's recommended only for those who can't control the final markup of their site/project as well as ninjas who want complete control over their markup.

Doh! The icon I want to use isn't showing up as a duotone icon!

Let's double-check a few things.

• Are you using the duotone-specific fa-duotone or fa-sharp-duotone family prefix?
• Duotone icons are only available with Font Awesome Pro — make sure you have an active Pro-level plan or a Pro license with access to v5.10.0 or greater for regular Duotone or v6.6.0 or greater for Sharp Duotone icons.
• We release icons pretty frequently these days. Make sure you're using the latest and greatest version, so any new icons you want to use are at your fingertips.
• If you've decided to host your own copy of Font Awesome, check that you've moved all of the files you need to use the icon you want. Also, double-check the paths to those files in your HTML's <head>.

Help! I can't target individual layers!

Make sure you're using the correct custom property values. Also, make sure you haven't defined a custom property that may be overriding things (check inline and in your custom CSS). We don't recommend writing custom CSS to target a specific class or pseudo-element — there are some differences between our Web Fonts and SVG versions of Font Awesome that can make this tricky.

Can I use Font Awesome styling with duotone icons?

Yes! You can use any of our styling options - like sizing and animations just to name a couple - with duotone icons. And if you're using the SVG + JS version of Font Awesome, our power transforms and layering let you do some pretty amazing stuff.

I'm using a subsetted Kit and the layers of my duotone icon layers look weird!

If you are using a Kit where you have selected subsetting, it is possible for the layers of your duotone icon to be rendered separately. This is most likely caused by attempting to use a duotone style that is not included in the subset. Here's the fix.

• Check the style of your icon and make sure the style you are trying to use is a part of your Kit subset.

Do duotone icons work with all browsers?

Yep! They work in all the browsers that we list on our Browser Support page.
