Duotone Depot

Duotone Depot draws each icon in two layers: a solid primary shape and a lighter secondary fill. In Figma both layers are bound to color variables, so recoloring the entire set to your brand takes one change. The 1,100 icons cover interface, commerce, devices, files, weather and travel, in sizes from 20px to 48px.

It works best on marketing pages, feature grids and onboarding screens where icons sit at larger sizes and carry some personality. The license allows commercial use for one designer and unlimited end products. The caveat: duotone loses its charm below 20px, so pair it with a simple outline set for dense toolbars.
