Keep the reader in control
A compact control panel starts or stops coloring, adjusts color strength, and restores the original pages.

The extension
Add color to manga in Safari, right where you’re already reading.
Manga Colorizer is an experimental Safari extension project for iPhone. The current prototype runs through the Userscripts extension and processes artwork on the device. It colors pages as you scroll, saves finished results locally, and lets you switch back to the original artwork.
Product focus
I set the direction around a simple reading experience: no artwork uploads, no paid colorization service, and no separate computer needed while reading. I test the output and reading flow, then use that feedback to prioritize quality, speed, and phone stability.
Make repeat reading lighter
Saved results can be revisited without running the model again. Processing pauses when the tab is hidden.
Balance quality with the device
The prototype integrates a pretrained colorization model. Iteration focuses on keeping ink and dialogue readable while managing processing time and memory on a phone.
Made for the reading flow
Start coloring. Keep scrolling. Return to the original whenever you want.
The panel keeps color strength, automatic processing, and the original-page toggle together. The capture shows the working controls in a local browser test.
Still in development
New pages take time to process. Color consistency, speed, and compatibility across readers are still being refined; generated colors may differ from the manga’s official palette.
