Black and white photos always remind us of the history or a period of time that never comes back. They are unique signs of an era and imply or tell us what happened at that time. However, adding color to old black and white photos can be much fun. Bringing an old photo or film back to life with colorization sounds really amazing, right? For example, colorize a black and white photo of a famous person in our history, like William Shakespeare or Coco Chanel. It seems like the people in the old photos are coming to our modern life and it feels like they're living in the same era as us.

There are some available tools for colorization now, including apps, online products and software. Among them, the most prevailing one should be colourise.sg which has been closed its service as of 1 Oct 2020. But now we have good news for you. We've found a good alternative and that is colourise.com, a great AI web tool to colorize old photos online for free.
Now let's have a try and see how to add color to our black and white photos step-by-step and bring our old photos to a new life.

Performance
I've colorized two photos with colourise.com and one is from the given examples and the other is a photo of Coco Chanel. When it comes to the first photo of butterfly, the result is pretty good. The color blending is quite natural and you won't doubt it is not a real shooting photo.

The second photo is a portrait but this web tool also handles it well. The hair color, skin color, cloth color are added naturally. It even deals with the light and shade and creates a three-dimensional effect. In a word, I'm very satisfied with the two outputs and I think this tool makes these old photos.
