Would you consider something like the following as an acceptable solution?

(1) Create a file which contains
        \input color
        \input /usr/local/texlive/texmf-local/tex/plain/local/colordef.tex
(2) Put that file in (say)
        /usr/local/texlive/texmf-local/tex/plain/local/my-color.tex
(3) In your source files, use
        \input my-color
    instead of
        \input color
?

I realize that it would require modifying your source files.


Alternatively, and I haven't tried this, if
        /usr/local/texlive/texmf-local/tex/plain/local/
precedes
        /usr/local/texlive/2021/texmf-dist/tex/plain/graphics-pln/
in however you have your system configured, then you might be able to
put the above file (in (1)) in 
        /usr/local/texlive/texmf-local/tex/plain/local/color.tex

Cheers.
