Still a valid rule: the master knows what set of warm colors they're
referring to, and will consistently mark koans according to that rule.
Their shorthand for it ("warm colors") is misleading, and Spock might
need to ask for the rule to be more precisely worded ("akhtbn iff all
pieces are colored in {red, yellow, orange}"), but the rule is valid.

When a student guesses "all warm", it similarly might be necessary to
clarify what "all warm" means. Again, though, the problem here isn't an
invalid rule, but a valid rule described with potentially imprecise
language (but still valid if adjudicated with appropriate precision).
