After Dark ships with an 169B optimized[^1] SVG favicon embedded into every page:

{{< highlight html >}}
{{< include "themes/after-dark/layouts/partials/head/favicon.html" >}}
{{< /highlight >}}

The favicon is a black-colored oblique triangle in the shape of a tepee as shown[^2] on the [Online Help](../online-help) [Overview](/). The center of the triangle uses negative space to give the illusion of a second equilateral triangle in the shape of a pyramid, or open fire, contained within.

The color of the icon can be modified by changing the `fill` attribute:

<style>
.hack figure {
  text-align: center;
  margin-top: 2rem;
}
</style>
{{< hackcss-grid class="-around" >}}
  {{< hackcss-cell class="-2of12" >}}

Adjust it from `favicon.html` in the site `layouts/partials/head` directory:

```
├── content
├── layouts
│   └── partials
│       └── head
│           └── favicon.html
├── static
```

If the file doesn't exist yet, copy it from the theme default:

```sh
$ mkdir -p layouts/partials/head
$ cp themes/after-dark/layouts/partials/head/favicon.html layouts/partials/head
```

If optimizing for platform experiences do so from within `favicon.html`:

{{< highlight go-html-template "linenos=inline" >}}
<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-status-bar-style" content="black">
<meta name="apple-mobile-web-app-title" content="{{ .Site.Title }}">
<link rel="apple-touch-icon" href="data:image/png;base64,{{ readFile "static/icon.png" | base64Encode }}">
{{< /highlight >}}
