Although the behavior is acknowledged, it is straightforward wrong, as one can't replicate the colors from an original GIMP palette file by inspecting the palette created by this loader alone - one has to be aware of this quirk instead. Strangely, that is even sorted of "documented" in the color names in the existing sample file, but it is plain wrong, as loading that file in GIMP will assign index 0 to the color currently named "index 3" in custom_gimp_palette.gpl" and so on. Rather, the colors specified in the palette file Inspecting the bytes generated by reading the file, it is possible to see that the 3 first colors in the palette do not correspond to the 3 first colors in the file (the first does, but it is (0, 0, 0) by a coincidence).
