Make a duotone photo

Map a photo onto two colours — one for the shadows, one for the highlights — the way a two-ink press would print it.

Mixing the inks…

◦ where two colors earn their keep

Six places duotone lands harder than full color

  1. 01 for spotify-vibe

    A navy/pink playlist cover

    The Spotify playlist cover aesthetic is a duotone — usually a deep blue mapped to a hot pink. Pick the Spotify preset, drop a portrait, hit download. Drop straight into a playlist or a band's social. Recognizable on sight.

  2. 02 for posters

    A two-color band poster from a single photo

    Show flyers don't need photo realism — they need contrast and identity. Punk preset (ink shadow, terracotta highlight) on a portrait gives you a flyer-ready hero. Print on cream stock, type the band name in big serif over the top.

  3. 03 for editorial

    A magazine-style portrait treatment

    Editorial portraits often go duotone for a 'considered' feel — navy/cream or moss/butter. The original photo's tonal information stays; the colors get unified into the magazine's palette. Pair with a serif headline.

  4. 04 for branding

    A team headshot gallery in your brand colors

    Team headshots from 14 different rooms with 14 different lights look like a unified team after duotone. Apply your brand's two colors as shadow/highlight; suddenly every face is part of the same visual system.

  5. 05 for moodboard

    Pinterest pins that look paid

    Mood-board pins with consistent duotone treatment get repinned more — they read as 'a curated set' instead of 'random photos'. Run all your reference shots through the same preset; suddenly your board feels like a designer's, not a hobbyist's.

  6. 06 for art

    A riso-feel portrait without a riso machine

    Risograph machines print one color at a time on absorbent paper, producing a textural two-color look. Riso preset (terracotta on cream) approximates that with fewer steps. Pair with the Halftone tool for the full risograph illusion.

Frequently asked

Does the photo upload anywhere? +

No. The duotone mapping runs pixel-by-pixel in your browser. Your photo never touches our servers — we don't run an image pipeline at all.

How does duotone differ from B&W? +

B&W maps every pixel to a grey based on luminance. Duotone maps every pixel to a *colored* value based on luminance, where the darkest pixels become your shadow color and the lightest become your highlight color. Same tonal structure as B&W, but with chromatic identity.

What does the midtone bias dial change? +

It bends the gamma curve of the luminance-to-colour mapping. Below 100 the midtones pull toward the shadow ink, so the image reads darker and moodier. Above 100 they pull toward the highlight ink, so it reads brighter and punchier. The shadow and highlight ends stay where you put them either way.

Can I match my brand colors exactly? +

Yes — the color pickers accept any hex code. For best duotone results, pick a dark-ish shadow color (under #555 luminance) and a light-ish highlight color (above #BBB luminance). Mid-tone shadow and mid-tone highlight will produce a flat, posterized result.

Why does my portrait look strange? +

Faces have specific tonal expectations — skin should sit between shadow and highlight. If your highlight is super-saturated (hot pink, lime), faces can look alien. Try the Editorial or Mono presets first to see clean output, then nudge from there.

How big is the export? +

Same dimensions as your source photo. JPG at 92% quality. For social-ready sizes, run through Crop & Resize afterward.
