Complete Guide: Duotone Image Maker
Everything you need to know about using this tool effectively
The Duotone Image Maker applies a two-color effect to any image. You upload an image, select a shadow color and a highlight color, and the tool remaps the image tonal range between those two colors. Dark areas take the shadow color, bright areas take the highlight color, and midtones blend between them. All processing happens in your browser.
