Can I use Lucide icons commercially?

Yes. Lucide is MIT licensed, which permits unlimited commercial use without attribution (though attribution is appreciated). The same applies to Heroicons, Phosphor, and Tabler.

How do I change the color of an SVG icon?

All quality icon libraries use currentColor for stroke or fill. Set the parent element's CSS color property, and the icon inherits it automatically. For example: style='color: #FF6B6B' on the container will make the icon red.

What size should icons be in a web UI?

16px for inline text icons, 20-24px for navigation and toolbar icons, 32-48px for feature illustrations. Always test at the target size — some icons lose clarity below 16px.
