of definitions by relation-theoretic "universal properties",
then I think that I am finally ready to illustrate the two kinds
of transition from a 2-adic view to a fully 3-adic perspective
on sign relations.  Let us pick one of the 2-adic denotation
tables for color words and work on that, for instance, this:

¤~~~~~~~~~~~~~~¤~~~~~~~~~~~~~~¤
| Object       | Sign         |
¤~~~~~~~~~~~~~~¤~~~~~~~~~~~~~~¤
| pink         | "rose"       |
| green        | "vert"       |
| yellow       | "jaune"      |
