Frequently Asked Questions
What is a duotone effect?
A duotone effect maps an image's brightness to two colors. Dark areas take the shadow color and bright areas take the highlight color, with smooth transitions in between. It creates striking, stylized visuals popular in graphic design and branding.
How do the color presets work?
Each preset provides a curated pair of shadow and highlight colors. Click a preset to instantly apply it. You can also choose Custom and use the color pickers to create your own unique combination.
Can I adjust the strength of the effect?
Yes. The intensity slider blends between the original image (0%) and the full duotone result (100%). This lets you create subtle tints or bold, fully stylized images.
