Here are my scary evals to use basic ANSI/vt220 color. N="$(printf '\033[')" x=30 for a in Bl R G Y B M C W # 4-bit Black Red Green Yellow Blue Magenta Cyan White do eval $a='$N'"'"$(( x))"m'" \ b$a='$N'"'"$((60+x))"m'" \ ${a}bg='$N'"'"$((10+x))"m'" \ b${a}bg='$N'"'"$((70+x))"m'" # bX=bright Xbg=background bXbg=brgt bgnd x=$((x+1)) done N="${N}0m" printf "$Y${Gbg}I am yellow on green.$N\n" I pasted this into my Android terminal, and it works as advertised.
