You can colorise your own photos by using this web form on Algorithmia: <a href="http://demos.algorithmia.com/colorize-photos/" rel="nofollow">http://demos.algorithmia.com/colorize-photos/</a><p>In my experience most colorisation looks very smudgy, does not "colour in between the lines", and generally seems to make things look sepia with low contrast - however I'd like to see this problem investigated more to see how good it can get - perhaps we could end up doing similar things for astral objects?
I was just thinking yesterday while reading <a href="https://news.ycombinator.com/item?id=13678255" rel="nofollow">https://news.ycombinator.com/item?id=13678255</a> (Street life in london) that I would like to see it colorized.
