Our new duotone style provide a version of every icon in Font Awesome that has two distinct shades of color. They're great for adding more of your brand or an illustrative quality to the icons in your project.
If you'd like to use duotone icons on the desktop, we currently recommend using the duotone-specific optimized .svg vector files. These can be found in the
/svgs/duotone folder of your "Font Awesome Pro for the Desktop" download. While the ligature-based font files we include are usually the easiest way to go, there are some technical limitations when it comes to multi-layered icons.
Adding a Duotone SVG Icon
In a desktop design application that supports working with
.svg files, open any of the individual duotone SVG icons found in
/svgs/duotone. You should see an SVG shape that contains two distinct layers.
Changing Layer Colors and Opacity
Once open, you can manipulate the opacity and color of individual layers in the SVG you opened.
After downloading "Font Awesome Pro for the Desktop", you can find and install and activate the duotone style at
/otfs/Font Awesome 5 Duotone-Solid-900.otf. The duotone typeface works like our other ligature-based
.otf fonts once installed and activated. There is one big difference however. Each icon's layer has been split into two separate glyphs, a
primary and a
secondary. You'll need to reference each in a separate text layer and then visually align those layers.
|Duotone Icon ||Separate Layers and Glyphs Needed|
Why have we separated duotone icons into two glyphs in the font file?
If you've followed the OpenType spec you may know about SVG in OpenType. It
allows colors, gradients, opacity and generally all the available options of
the SVG format to be embedded in an OpenType font file. You are already
familiar with this technology if you've ever used an emoji on your Android or
iPhone device. If you haven't used an emoji, seriously; what have you been
doing on your phone?
We experimented with this technology while we were adding the duotone feature
and found it had one major drawback: it doesn't inherit color. In desktop apps
that we tried (Photoshop, Illustrator, and Sketch) the opacity worked well but
the icons always remained a boring gray, unable to be changed unless you broke
it up into outlines. This ability to inherit color is supposed to
work(opens new window) and
does in most Internet browsers. In desktop apps, though, it trips over its
shoelaces and face-plants into failure.
