Strange color in face when inference

[phuongpropk05]

Hi, I really like your project; it's so awesome.
Anyway, I got some strange color (blue tinted photo under the eyebrown, ...) in the face of output when inferring with model vtoonify_d. Can you give me some suggestions to fix this? If possible, I would appreciate.
Here is some output with strange color (blue color)

I didn't encounter such issue and have no idea how it happens.
Maybe you can use some postprocessing tool like Photoshop to remove the blue color?
