You can simplify a little bit the line:
grep -i "^[ABCDEFOIS]{6}$" /usr/share/dict/words | tr '[:lower:]' '
[:upper:]' | tr 'OIS' '015' |awk '{print "#" $0}'

You can replace ABCDEF with A-F

@sicpier , I was just coming here to post something similar, but grep
doesn't work on my Ubuntu distro. I'd need egrep or grep -P

Do you like backslashes? Then sed is the tool for you:

sed -n 's/^[a-fios]\{6\}$/#\U&/p' /usr/share/dict/words | tr 'OIS' '015'

-n ignores non-matching lines; /#\U appends the # and upper-cases
matching lines.

edit: forgot & could be used in place of a capturing expression.

For those of you with 256color terminals, here's one that shows each
color:

sed -n 's/^[a-fios]\{6\}$/\U&/p' /usr/share/dict/words \
  | tr 'OIS' '015' \
  | gawk --non-decimal-data \
         '{print "\033[48;2;" \
                 ("0x"substr($0,1,2))+0 ";" \
                 ("0x"substr($0,3,2))+0 ";" \
                 ("0x"substr($0,5,2))+0 "m" \
                 "       \033[0m " \
                 $0}'

I thought about leaving the text inside each color block, but I'd
want to invert the color for the text FG, which would take us even
further from a "one-liner". I'm already wishing I could loop over
each color-component inside the pipe, but I'd need to keep the hex
form for the output:

sed -n 's/^[a-fios]\{6\}$/\U&/p' /usr/share/dict/words \
  | tr 'OIS' '015' \
  | { while read VAR <&0; do \
        echo $VAR | fold -w2 | xargs -n3 bash -c 'printf "\033[48;2;%03d;%03d;%03dm      \033[0m '"$VAR"'\n" 0x$0 0x$1 0x$2'; \
      done; }

I bet someone who knows Perl well could do an all-in-one.
