Hmmmm

Well of course no information is conveyed by sameness of color.  But there
are differences in color that do not convey information.  And there is
information convey in other ways.   It is only information conveyed by
difference in color that the provision applies to.

I thought about color coding.   But color coding is too pedagogical I
believe.  It is a good theoretical construct but too narrowly interpreted in
practice.   And it is more technical jargon when we said we would try to use
plain English as we can.
