The original discussion about it happened in emacs devel so there was
no bug number. The commit is:

    9ad0f1d15c06eb07dfbd9bd3e3b8a0d747942152

and if I’m reading the tags correctly it is definitely in Emacs 26.2.

What I’d suggest to Evan is to delete the colour file, as it’s
possible Emacs 26.1 has left a corrupt version:

    rm $HOME/Library/Colors/Emacs.clr
    
Then restart Emacs twice. The first time it will recreate the file and
probably not emit any error, the second time should let us know if the
error has gone.
