Public bug reported:

enfuse sometimes produces false colored pixels around dark regions using
the default options.

When using the option "--blend-colorspace=identity" the artefacts don't
show (at least with the attached example images).

Tested with version 4.2  and 4.3-e93b798a0c5f. The artefacts show with
both versions, although there are differences.


Attached are sample images and the result images after using the included script. There is also a self-compiled binary of the enfuse version 4.3-e93b798a0c5f and a text file ("Info.txt") containing info about versions, operating system and hardware. 

The result images 
"default.tif" and "default_dev.tif"
are the images made with default options,
the images 
"identity.tif" and "identity_dev.tif"
are made with the option "--blend-colorspace=identity".

The images
"default_dev.tif"and "identity_dev.tif" are made with the development version 4.3-e93b798a0c5f
