Wk1 Hand Colored AI Algorithm

Hi,
I selected a photo of my husband and I.  I used the grayscale on GIMP to turn it into black and white.  I then uploaded the photo through the website and it added color to it.  It doesn't look like the original but close to it.  It looks a bit old fashioned now.
I will give you all variations, so you can see the way it transformed.
This is the original picture.

This is the grayscale I added through GIMP, to make it black and white.  This picture I submitted through the Algorithm website. 

This is what the Algorithm website produced.  It added color to it, making it a bit different than the original but still very nice.  I like that it looks weathered.
