    How duotone works

    Each pixel's brightness is measured and re-mapped: dark areas take your colour, bright areas move toward white, and mid-tones blend between. Because it's driven by luminance, the image keeps its structure while adopting a single, unified colour identity — great for a cohesive brand look across many photos.

    FAQ

    How do I make a duotone image?

    Drop an image, pick a tone colour, and click Apply — the image is re-mapped onto that colour. It runs in your browser.

    Can I get the classic brown look?

    Pick a warm brown, or use the dedicated Sepia tool for the standard vintage tone.

    Part of: Turn a photo into poster art

    Flatten the tone before you colour it. Posterising after a duotone gives you banded duotone, which is rarely what anyone wants.

    1. 1 Posterize Cut the tonal range to a handful of steps
    2. 2 Duotone Map the result onto two colours
    3. 3 Gradient map Or onto a whole gradient, for more than two
    4. 4 Halftone Add the print-dot texture
    5. 5 Add outline Outline it if it will sit on a coloured ground
