What types of images work best?

Images with strong contrast — portraits, architectural shots, or product photos against simple backgrounds — produce the most striking duotone results.

Do you have color combination recommendations?

Spotify style: deep blue + bright yellow. Vintage: dark brown + cream. Cyberpunk: deep purple + neon pink. Nature: dark green + bright lime.

Is the original color information preserved?

No. Duotone converts the image to grayscale first, so original color data is removed.

Does it work with transparent PNG files?

Yes. Transparent areas are preserved and the duotone effect is applied only to opaque pixels.

What format is the output saved in?

PNG. Transparency is preserved if the source image has an alpha channel.

Duotone Tips & Use Cases

Social Media Content — Apply Brand Colors

Use your brand's primary colors as the duotone palette to give portraits or product photos a consistent branded look. Apply the same duotone settings across a series of images for cohesive campaign content.

Poster & Banner Design

Duotone effects create high-impact visuals with a limited color palette — ideal for concert posters, event banners, and album covers. When overlaying text, choose colors that contrast well with the chosen tones.

Website Hero Images

Apply a duotone to your website's hero background image to emphasize brand colors while keeping white text readable. A dark shadow color works especially well as a base for white headline text.
