What this tool does
Duotone maps an image's tonal range to two colors — one for the highlights and one for the shadows — creating a bold, graphic effect popular in branding, editorial photography, and social media. PixelForge applies your chosen shadow and highlight colors to your entire image library in one batch, giving you a consistent visual treatment across a full collection.

Frequently asked questions
What is a duotone?
A duotone maps a grayscale image to a two-color gradient — one color for the darkest pixels (shadows) and another for the brightest (highlights). Midtones blend proportionally between the two colors, creating a graphic, two-color treatment.
What colors should I use?
High-contrast pairings work best — a dark color for shadows and a bright or saturated color for highlights. Brand colors often work well. Complementary color pairs (opposite on the color wheel) create vivid, dramatic results.
Will the output still look like a photo?
Yes — all tonal detail is preserved, just mapped to your chosen color range. The result looks like a stylized, color-filtered photo rather than a flat graphic.
Is duotone a Pro feature?
Yes — duotone effect is available on Pro and Business plans.
