You can draw a filled polygon (rectangle) using \D'P ...'
covering the whole page at the beginning of each page,
before outputting any text. Example:
.\" a4 land
.\" ----------------------------------------------------------------
.nr PL 21.0c \" A4 landscape height
.nr PW 29.7c \" A4 landscape width
.pl \n(PLu
.po 2c
.ll \n(PWu-\n(.ou-\n(.ou
.gcolor green
.\" ----------------------------------------------------------------
.\" set up a separate environment for headers and footers
.\" to avoid interference with the running text
.ev 1
.vs 0
.lt \n(PWu-\n(.ou-\n(.ou
.fcolor black
.gcolor yellow
.ev
.\" ----------------------------------------------------------------
.de BP
.ev 1
\Z'\h'-\\n(.ou'\D'P 0 \\n(PLu \\n(PWu 0 0 -\\n(PLu''
.sp |2c
.ev

.de EP
.ev 1
.sp |\\n(PLu-1.5c
.tl '\\n[year]/\\n[mo]/\\n[dy]''\\n%'
.bp
