A third option is Phosphor Icons, a flexible open-source icon family that pairs especially well with the approach in this article. It offers over 1,500 icons, each available in six weights — Thin, Light, Regular, Bold, Fill, and Duotone — so if you like the two-tone look from the PowerShell/Font Awesome method above, Phosphor gives you duotone SVGs natively without any scripting to recolor them. Everything ships as clean SVG (designed on a 16×16 grid to scale cleanly), it's MIT licensed and free for commercial use, and you can adjust color and weight to match your brand before uploading to a topic, catalog item, etc. Browse the full set here: Phosphor Icons.
