Duotone Effect — how it works
Map a photo onto two colors — the Spotify-style duotone look.
How duotone works
The photo is converted to brightness, then every brightness level is mapped onto a gradient between two colors: the darkest pixels take the shadow color, the brightest the highlight color, everything else a blend. Detail and contrast stay; the palette becomes entirely yours.
Picking colors that work
Duotones read best with a dark, saturated shadow color and a light, bright highlight — navy and pink, ink and lime, purple and orange. Two colors of similar lightness flatten the image. The Heat preset adds a third color in the middle for a tritone.
Where to use it
Duotone photos unify mismatched images in one brand palette, make text on top of photos easier to read and look great on posters, covers, hero sections and social templates.
