About duotone filter

A duotone maps every pixel onto a gradient between two chosen colours, flattening the photo into a bold two-tone graphic. It is the look of many editorial covers and gig posters, and here it is a single local operation you can apply to any picture.

Frequently asked questions

What is the best colour pair?

High contrast works: dark navy with gold, deep green with cream, black with a fluorescent accent. Very similar colours produce a flat, muddy result.

Does the photo shape change?

No. Only the colour mapping changes; dimensions and composition stay intact for an effortless consistent feed aesthetic.
