Using AI to colourize black and white drawings

I found this deep learning project. It is meant and trained to colourize old black and white photos. And it does a very good job. But what it does when I use black and white drawings?

If the picture depicts a person it works pretty well. Although it loves yellowish red tones. But with other things, the results are not so good.

The left is original and the right is colourized by AI.
