How the AI Colorizer Works
DERSTY.ai includes a built-in Colorize mode in its AI studio. To colorize a photo, switch to the Colorize tab, upload your black-and-white or grayscale image, and click the colorize button. The AI analyzes your photo and reconstructs color based on context — faces, skies, foliage, clothing, and backgrounds all receive appropriate, natural tones.
You can also add an optional color guidance prompt to steer the result. For example, describing "warm golden-hour tones" or "realistic 1950s film colors" will influence the AI's colorization style, giving you more creative control without needing to manually edit anything.
Once colorized, you can download the result instantly as a high-quality PNG. Each colorization uses credits — new accounts start with free welcome credits, and daily rewards let you keep colorizing at no cost.
Restore Old Photos Before Colorizing
Many old or scanned photos come with visible damage — scratches, dust, fading, noise, and deterioration that accumulated over decades. DERSTY.ai includes an optional Restore toggle that lets you repair this damage before the colorization step, all in a single click.
When enabled, Nano Banana 2 first analyzes the image for signs of degradation — reducing scratches, noise, and fading, improving sharpness, and enhancing overall clarity — without altering the original scene, faces, or composition. It then applies colorization to the restored image, producing a clean, vibrant result from what might have been a badly damaged original.
Repairs visible scratches, dust specks, and surface imperfections from aging or scanning.
Smooths grain and digital noise common in old scans and degraded negatives.
Restores contrast and detail lost to time, UV exposure, or improper storage.
Restore and colorize in a single operation — no manual editing or separate software required.
The Restore toggle is off by default — standard colorization behavior is unchanged for users who don't need it.
