One must be wrong. They can't both be correct. I just don't know which.
Or maybe both aren't correct. Anyway their syntax can't be that
different.

Anyway, no matter how you look at it, there is at least something wrong
with at least one of items in at least one of the modes!

If you say one item looks great, then you have to explain how another
item can use a different coloring rule.
