Re: plain TeX: "color" also colours page number

you can fix the page foot to be black but to get any reliable output at all
from the document you also need to fix all the unclosed groups

### simple group (level 17) entered at line 121 ({)
### simple group (level 16) entered at line 113 ({)
### simple group (level 15) entered at line 106 ({)
### simple group (level 14) entered at line 98 ({)
### simple group (level 13) entered at line 91 ({)
### simple group (level 12) entered at line 83 ({)
### simple group (level 11) entered at line 76 ({)
### simple group (level 10) entered at line 68 ({)
### simple group (level 9) entered at line 61 ({)
### simple group (level 8) entered at line 53 ({)
### simple group (level 7) entered at line 46 ({)
### simple group (level 6) entered at line 38 ({)
### simple group (level 5) entered at line 31 ({)
### simple group (level 4) entered at line 23 ({)
### simple group (level 3) entered at line 16 ({)
### simple group (level 2) entered at line 8 ({)
### simple group (level 1) entered at line 3 ({)
### bottom level

I closed them all at the end although it's not clear why you have a {
before every \textcolor
so perhaps you wanted to close some earlier.


So you need

\footline={\hss\textcolor{black}{\tenrm\folio}\hss}

as the first line, to normalise the color in the page foot and

}}}}}}}}}}}}}}}}}%??????????????????

just before \bye to close all the open groups
