It's ugly. The first point is that ( and ) are special characters and
if unquoted are isolated tokens that have special syntax. So in order
to get [ to see them as arguments, you have to quote ( and ). But the
quoted characters are ordinary characters and to make them be separate
arguments to [, you have to separate them from the adjacent arguments
with spaces. So this version works:
if [ \( "$1" = "yes" -o "$1" = "YES" \) -a \( "$2" = "red" -o "$2" = "RED"
\) ]
then
echo "Yes, it's red"
else
echo "No, it's not red"
fi
