tlmgr: packages "not present in repository"
a "package" to tlmgr is a unit of files that are installed together it does not necessarily relate directly to a latex "package" (it may just contain fonts, or a binary program, for example) In the case of color
that is part of the texlive graphics
package. (an easy way to see the texlive package any file is contained in is to look at the ctan page for the file eg
https://www.ctan.org/pkg/color
which shows the miktex and texlive package that it is contained in.
Actually graphics
is part of the latex "required" distribution, so if you have latex at all you should already have the graphics packages including color.
Here is a complete list about the "missing" packages:
- fontenc: part of latex distribution
- lmodern: is called "lm"
- graphicx: part of the "graphics" package (which is part of "required")
- lscape: part of the "graphics" package
- otf: could be japanese-otf, font-otf, or japanese-otf-uptex or any combination thereof
- plext: part of platex, so maybe also of uplatex
- verbatim: part of the "required" package
