Trondmm, sadly no, thats not really how it works, the file is trained by images they used who created the "coloring AI". There should be a way to teach it but I don't know how and didn't get answer when asking them.
Amayra, I hope someone will port it, there is a port off another system but its not free and they take pay for every image you colorize and they are not as good (in my eyes)
