I decided to test this with photos from my grandfather where were before WW2. Did this software colour the images... yes... was it great... no. There are greenish horses in the photos.

The resolution upload and file size limit is quite low at only 3000 x 3000 and 5MB.

Also as these are scans from old photos there were scratches and nicks so I tried their damaged pics tool and it took the image and removed ALL the scratches and issues but now the image is so low res/blocky it actually worse than before I started.

Does it do the job... yes... does it do the job well... no.
