I want to use a specific palette to make it strictly index color.

1. There is a bug, in which case you can report it (but with the actual image and palette)
   
2. Your expectation of "closest color" is not the same as Gimp's. This wouldn't be surprising since looking at the comments in the source code (see here around line 31) Gimp  doesn't match colors in RGB but in CIE L*a*b space (and the comment at line 22 hints that in Gimp3  this will be done using the linear and not gamma-encoded values).
   

I think this is a bug, so I would like it to be fixed.

By the way, I am using LinuxMint and Windows11
and the same issue occurs on Gimp 2.10 and 3.0.0RC1.

Here is the image that actually had the problem.

How can I add palette information (gpl)?
