Point taken, and that colour name is typoed anyway :(
It should have read ovgatetripbi'dmul , and apologies if that sounds like
a medication <me giggles>

That isn't actually the flaw I was thinking of, In fact looking over my
posting I can also see another flaw
I didn't notice when starting to think about this, relating to a
possible ambiguity that needs resolving.
