indeed!
the exclusive range {green TO red} matches to the "lemon yellow"
hence, the negation suppresses it from appearing
fq=-color:{green TO red}
then you need to suppress eg black and white also
fq=-color:({* TO green} {green TO red} {red TO *})
I have no control over the

You don't need to control possible values, you just suppressing any values
beside of the given green and red.
Mind that either green or red passes that negation of exclusive ranges
disjunction.
