Hello,
I just recently found this software and it does an amazing job to stitch photos. However when I create an output I get some red artifacts at some areas that are not on the original photos.
Is there a way to fix or prevent this?

That looks like the pixel data is still there but the color profile of
the original image were discarded. But it is only a rough guess: I can
completely wrong...

Kind regards,

  Try with the option
        --blend-colorspace=IDENTITY
in the enblend process

Thank you

   Yes LV360Tour, here is how:

   In case you have your Hugin in the "simple" interface, go to "advanced". "Specialist" will work also. My hugin shows you the Portuguese (Brazilian) interface, but this will work for you :)
   It is on the fourth menu:

Once with the specialist interface you will have access to the Stitching tab (Montador in my picture), it is the last. Select this tab, go down and click in enblend options, where your actual option(s) should be:

    I once had those red points in the pano, but they are much more than in your case. And it took lots of time!

    Let us know if this solved your problem.

   regards
