One icon, two layers of colour
Duotone is a style of the Core set, gathered here as one collection: 1,057 of the 6,286 Core icons — the ones that have a filled counterpart — can be rendered Duotone, their filled rendition at 24% opacity under the regular stroke. They are the same icons, in a fifth style — not a separate set. Duotone downloads are included with Pro or the Icon Pack.
No filters, no fake fills: Duotone composes each icon's two real artworks — the filled rendition the set's authors drew, laid at 24% opacity under the regular stroke rendition. Icons without a filled counterpart simply don't offer the style — which is why the collection is 1,057 icons, not 6,286.
The stroke rendition on its own — the icon as the whole set is drawn.
The filled rendition on its own — real filled artwork, drawn by the set's authors.
Both together: the filled rendition at 24% under the stroke — depth without a second colour.
Duotone recolours like every other style — both layers take your colour. Shown here in #B026FF.
Every icon below is free to browse and free in its other styles (PNG and WebP up to 128px, transparent background). The Duotone style itself is a Pro feature at every size — Pro subscribers and Icon Pack holders download Duotone files from each icon's own page; see pricing.
