Not that I am aware of. That sounds more like a style score than
something indicative of spam/ham, though. Have you seen a pattern?
yeah sometimes I get price lists I never asked for from suppliers I've never
heard of and they often use multi-coloured text for loudness. These emails
are scoring too low.
I doubt it is indicative of just spam. I have plenty of people who use
47 colors in legitimate emails as well. Happy to test a rule if you
think you have an idea but to me it sounds like a waste of time.
