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.
