How to use Create a Two Color Image
- 1. Upload the image. Drop in the photo or graphic you want remapped to two colors. It decodes so each pixel's brightness can be measured for the duotone mapping.
- 2. Set the Shadow color and Highlight color. Pick a Shadow color for the darkest pixels and a Highlight color for the brightest ones. Every pixel in between gets a blended shade along the gradient from one to the other.
- 3. Download the duotone image. Save the result once the preview shows the image recolored entirely between your two chosen colors, replacing the original color information with the duotone gradient.
When to use Create a Two Color Image
Create a Two Color Image remaps a photo to a duotone built from two colors based on each pixel's brightness, replacing full color with a shadow-to-highlight gradient between the two. It is for a graphic, branded look rather than natural color adjustment.
- Matching a two-tone brand style. A brand's visual identity uses a specific pair of colors for all its photography, and mapping product or event photos to that duotone keeps the whole gallery consistent.
- Creating a poster-style portrait. A concert or event poster wants the bold, high-contrast duotone look popular in gig art, achieved by mapping a portrait photo to two strongly contrasting colors.
- Designing a print piece with limited ink colors. A print run using only two ink colors needs source photos converted to match, and previewing the duotone result here confirms how the image will look before sending it to print.
