FAQ
Does it work on partially colored images?
It works best on fully black-and-white or greyscale images. Partially colored images may have inconsistent results.
Can I control the colors used?
The AI automatically determines the most realistic colors. For full color control, use the Custom Editor in Gen AI after colorizing.
Should I restore old photos before colorizing?
Yes. Use Old Photo Restoration first to remove damage, then colorize for best results.
Should I colorize before or after forging?
Always before. Complete all editing first, then forge.
