Duotone Image Tool
Create a two-color duotone effect using custom shadow and highlight colors.
Create a Duotone Image
The tool maps dark pixels toward your selected shadow color and bright pixels toward your selected highlight color, creating a consistent two-color effect while preserving image structure.
Example
A black-and-white portrait can be transformed using dark navy shadows and green highlights to create a branded graphic while keeping the facial details visible.
Factors That Affect the Result
Images with strong tonal contrast usually create clearer duotone results. If the original image is very flat or low contrast, the two selected colors may blend more evenly and produce less visual separation.
Frequently Asked Questions
Can I use any two colors?
Yes. Choose custom shadow and highlight colors.
Does the tool change image dimensions?
No. The original canvas dimensions are preserved.
Is processing local?
Yes. The image is processed in your browser.

Creating a Duotone Effect
Duotone maps image tones to two selected colors, producing a controlled graphic style. Strong contrast between the chosen colors usually gives clearer results. Check important facial or product details before export, because very dark or very similar tones can reduce separation and make the subject harder to read.
Creating a Duotone Effect
Duotone maps image tones to two chosen colors, creating a consistent graphic style. High contrast source images usually produce clearer results. Test both colors for readability and brand fit, especially when the image will sit behind text or interface elements.
Technical Method and Practical Limits
A duotone effect maps image tones between two selected colors, usually using luminance as the underlying tonal guide. Contrast in the source and the chosen color pair strongly influence legibility and preservation of highlight and shadow detail.
